As part of a larger project to revise the systematics of lower Westphalian floras of Nova Scotia and New Brunswick, the sphenopsid taxa are presently reviewed. We recognize 15 species, of which one, Annularia stopesiae, is new. Detailed synonymy lists allow a refinement of the stratigraphic and geographic ranges of these species. Scant attention has been paid previously to Canadian species in the European literature. For example, Annularia latifolia was described later from Europe as Annularia jongmansii. The identical composition of Westphalian floras from Canada and western Europe is striking.
La révision de la flore du Westphalien inférieur de Nouvelle Écosse et Nouveau Brunswick a été continué à présent avec les sphénopsides. Nous avons reconnu quinze espèces, y compris une nouvelle, Annularia stopesiae. L’analyse des synonymies a permis établir l’extension stratigraphique ainsi que la répartition géographique de cettes espèces. On constate que les auteurs européens ignoraient souvent les espèces décrites au Canada. Un example à citer est Annularia latifolia qui est la même espèce qu’Annularia jongmansii décrite en Europe. On constate ausssi, une fois de plus, que la flore westphalienne est identique pour l’Europe occidentale et Canada.

1 While engaged in the taxonomic revision of upper Namurian to middle Westphalian floras of the Maritime Provinces of Canada, it became apparent that certain forms of the sphenopsid fossil-genera Annularia and Asterophyllites needed special attention in a broader context. Some of the species of these genera were first described from Canada, but have been referred to only rarely or not at all in the western European literature, despite the palaeogeographic proximity between the Maritime Provinces and Europe, the British Isles in particular. Conversely, some species described from Europe were used only sparingly in Canada and the United States. A more thorough comparison was clearly required. This has led to the recognition of several synonyms, thus leaving a smaller number of accepted species. The oft-quoted resemblance of the Westphalian floras of Canada with those of western Europe is reinforced by a thorough taxonomic revision. Several of Bell’s (1944) and Matthew’s (1906a, b) specimens are refigured from museum collections. Additional material from New Brunswick and Nova Scotia is also documented.
2 From the classic Fern Ledges locality at Saint John, New Brunswick, Dawson (1861) described as new Asterophyllites parvulus (corrected spelling by Jongmans 1914b; originally Asterophyllites parvula), which Stopes (1914) compared with Asterophyllites grandis and Bell (1944) synonymized with Asterophyllites charaeformis. Dawson (1862) introduced Annularia acicularis and Annularia latifolia (both initially attributed to Asterophyllites). Stopes (1914) compared Annularia acicularis with Annularia radiata and Asterophyllites equisetiformis, and Annularia latifolia with Annularia stellata. Another species introduced by Dawson in 1862 was Asterophyllites? scutigerus (corrected spelling) for what appear to be stems of Calamites (Dawson’s pl. XIII, figs. 18, 20). He also recorded a strobilus (his pl. XIII, fig. 19) and Annularia acuminata, a species that Dawson refigured in 1871 as Sporangites acuminata and comprises sporangial clusters. Dawson (1871) additionally described Asterophyllites lentus (corrected spelling by Matthew 1906a). One of Dawson’s specimens of Asterophyllites lentus was refigured by Stopes (1914) as Asterophyllites sp. and compared with Annularia radiata. Bell (1944) synonymized Asterophyllites lentus with Annularia acicularis.
3 Also from Fern Ledges, Matthew (1906a) described Asterophyllites fasciculatus. As Stopes (1914) pointed out, this name was preoccupied, having been used previously by Lesquereux (1879–1880) for a different species from Clinton, Missouri. Although fragmentary and poorly preserved, Matthew’s material might be attributable to Asterophyllites longifolius. Matthew (1906a) described two additional specimens as Asterophyllites? fissus and Annularia longifolia mutation leavittii. The former is here referred to Asterophyllites longifolius. Stopes (1914) assigned Annularia longifolia mutation leavittii (figured photographically in Matthew 1906b, pl. IX) to Annularia stellata, but we regard it as belonging to Annularia inflata Lesquereux. Two specimens recorded as Annularia recurva by Matthew (1906a) were referred to Annularia acicularis by Bell (1944), albeit with doubt. Stopes (1914) regarded these two specimens and a more fragmentary one, described by Matthew (1906a) as Annularia? ligata, as indeterminable; we concur. Annularia latifolia var. minor, as described by Matthew (1906a), was compared by Stopes (1914) to Annularia stellata, but retained in Annularia latifolia because of a (slightly) greater width of leaves in the Canadian material. We regard Annularia latifolia var. minor as a synonym of Annularia galioides. We also assign to Annularia galioides a specimen from Fern Ledges figured by Bell (1966, pl. VII, fig. 3) as Annularia latifolia.
4 Among the sphenopsids from Fern Ledges, Stopes (1914, pl. V, fig. 7) figured a specimen as Annularia sphenophylloides. We agree with Bell (1944), that this specimen was misidentified and should be referred to Annularia latifolia.
5 Bell (1944) incorporated material from New Brunswick with his description of fossil plants from the Cumberland Basin in northern Nova Scotia. He discussed Annularia latifolia extensively, and regarded Annularia latifolia var. minor of Matthew (1906a) as falling within the range of variation of Annularia latifolia without necessitating a separate variety. As mentioned above, we regard Annularia latifolia var. minor as belonging to Annularia galioides. Bell (1944) introduced two new species, Annularia aculeata and Annularia asteris. The former was typified by material from Inverness County, Cape Breton Island, Nova Scotia, whereas the latter came from Tynemouth Creek, near Saint John, New Brunswick, from a level equivalent to that at Fern Ledges. Annularia aculeata is here regarded as founded on a mixture of Annularia ramosa, Asterophyllites grandis and Asterophyllites charaeformis (see below). Bell (1944, 1966) also figured two specimens from Springhill, Nova Scotia, as Annularia stellata forma longifolia. These specimens are refigured here and described as a new species, Annularia stopesiae.
6 The Canadian record contains fewer species than the publications suggest. Our critical revision emphasizes its similarity with the western European record.
7 The specimens used for the current revision are in the collections of the Geological Survey of Canada, Ottawa (catalogue numbers preceded by GSC) and the New Brunswick Museum (NBMG). More complete information about GSC localities can be found in the memoirs published by Bell (1938, pp. 108–115; 1940, pp. 133–139; 1944, pp. 111–118; 1962, pp. 63–64).
8 As in our previous revision of the Lycopsida (Álvarez-Vázquez and Wagner 2014), partial lists of synonymy are provided with special emphasis on types and listing all the illustrated records from Canada and the United States for the Middle Pennsylvanian time interval. European records are selective. However, all synonyms as accepted by the present authors are included. Descriptions, comparisons and remarks are included as well as stratigraphic and geographic distributions, and occurrence in Canada and the United States. Stratigraphic occurrences are given in accordance with the western European regional chronostratigraphic subdivisions of the Pennsylvanian Subsystem.
9 Annotations in the synonymy lists follow those of Cleal et al. (1996 — shortened/simplified): * = protologue; § = first publication of currently accepted combination; T = others' photographic illustrations of the type material; ? = references to doubtful specimens due to poor illustration or preservation; p (pars) = only part of the specimens published belong to the species; v (vide) = the authors have seen the specimen(s); cf. = comparable; k = reference includes cuticular evidence; acc. to = according to.
10 The various species recognized in the Maritime Provinces will be dealt with in alphabetical order within the adpression genera Annularia and Asterophyllites, which are based on leaves.
11 TYPE: Annularia spinulosa Sternberg 1821
12 REMARKS: Annularia and Asterophyllites incorporate small Calamites-type articulate axes bearing leaf verticils at each articulation (node). Both genera have singleveined leaves which are more or less united at the base in each verticil. However, the leaves of Annularia are linearlanceolate, lanceolate or spatulate, with the broadest part in the middle of the leaf or near the apex; Asterophyllites has narrower, almost parallel-sided leaves, with the broadest part in the lower third, and a pointed apex. Verticils of Annularia are usually found as dorsi-ventral adpressions spread out on the bedding plane; leaf whorls in Annularia are either isophyllous or markedly anisophyllous. In contrast, the leaves of Asterophyllites are usually preserved flattened sideways, parallel to the axis. However, in practice, it is not always possible to separate Annularia from Asterophyllites in view of the important role played by preservational characters.
13 Tables 1 and 2 summarize the morphological characters and numerical values of measurements for the different species of Annularia and Asterophyllites.
(Figs. 1a–e)
Excludenda:
14 DESCRIPTION: Ultimate axes 0.2–0.3 mm wide, inserted suboppositely at a wide angle (80–90°). Internodes 2.25–3 mm apart, bearing closely spaced verticils that overlap slightly in spread-out preservation. Verticils with 8 to 10 leaves of equal length and united at the base so as to form an annulus; they are stiff, narrow, with nearly parallel sides, though sometimes slightly wider across the middle; apex acuminate. Dimensions: 2–4.5 mm long at 0.20–0.25 mm width; length/breadth ratio = 10–18. Vein not visible.
15 REMARKS: Although widely reported, particularly in the United States, Annularia asteris has been generally misidentified. Bell (1944, pl. LXVII, fig. 3; pl. LXVIII, fig. 5) figured only one specimen (the holotype) from Tynemouth Creek, New Brunswick. Although well preserved, additional material is required to show the full range of morphological variation.
16 In addition to Bell’s holotype, we figure as Annularia asteris a specimen from Fern Ledges at Saint John, New Brunswick, which is preserved on the same bedding plane as the type of Asterophyllites parvulus (= Asterophyllites charaeformis) (Matthew 1906a, pl. VI, fig. 3). At first, we considered that both specimens might belong to a single species (as Matthew may have thought). However, Asterophyllites charaeformis has small, reflexed, thread-like leaves that are preserved parallel to the axis, whereas Annularia asteris displays (equally small) leaves that are most commonly preserved in spread-out (dorsiventral) position (see Figs. 1a–c; parts of the holotype).
17 Annularia asteris was recorded from West Virginia as Annularia minuta by Wood (1869) and Lesquereux (1884a). However, this name had been used already by Brongniart (1828a, pp. 155, 175) as a nomen nudum referring to specimens from the Stephanian of Terrasson, Aquitaine, southwestern France. Brongniart’s specimens were illustrated by Zeiller (1892, pl. XI, figs. 2, 3), who referred them to Annularia spicata, a late Stephanian species. We concur.
18 COMPARISONS: Bell (1944) compared Annularia asteris with Annularia galioides and its synonym Annularia cuspidata. The narrow, almost thread-like leaves of Annularia asteris are quite different to the more fleshy ones of Annularia galioides. Also, the leaves of the latter species are oblanceolate and possess a smaller length/ breadth ratio. Annularia minima is another similar smallleaved species. However, its leaves are not as thread-like as those of Annularia asteris. Leggewie and Schonefeld (1961) observed that the leaves of Annularia minima are widest around the middle. Annularia ramosa possesses larger, linear-lanceolate leaves that have a length/breadth ratio between 23 and 26, and a more fleshy appearance.
19 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Annularia asteris has been rarely recorded. In Europe, the type material of the synonymous Annularia subradiata is from upper Namurian (Yeadonian) strata of the Assise d’Andenne, Belgium. The specimen (assigned to Annularia ramosa) by Josten (1991) came from the Langsettian of the Ruhr District, western Germany. Kidston et al. (1917) recorded this species (misidentified as Annularia spicata) from the lower Bolsovian of the Forest of Wyre in England. Crookall’s (1969) specimen came from the Bolsovian of South Staffordshire, also in England. The material of Purkyňová (2000) originated from Kinderscoutian to Langsettian strata of the Upper Sile-sian Coal Basin, in the Moravian part of the Czech Republic.
20 OCCURRENCE IN THE MARITIME PROVINCES: Cumberland Basin (Nova Scotia): Bell (1944): locality 1087 (one piece without catalogue number); locality 1088 (GSC 10094 — together with Asterophyllites charaeformis + GSC 10099 + GSC 10100 — cf.; poorly preserved + GSC 10102 — cf.; together with Calamites sp. + GSC 10103 — cf. + GSC 10104 — cf. + GSC 10105 — cf.; together with Calamites sp. + GSC 10109). Tynemouth Creek (New Brunswick): Bell (1944): locality 642 (GSC 9805 — holotype; here Figs. 1a–c; together with Laveineopteris polymorpha on the same specimen). Fern Ledges (New Brunswick): New Brunswick Museum collection: NBMG 3435 + NBMG 3436 (see Figs. 1d–e; together with Asterophyllites charaeformis and Alethopteris sp. indet.).
21 OCCURRENCE IN THE UNITED STATES: Michigan: Arnold (1934, 1949). Utah: Tidwell et al. (1988). West Virginia: Wood (1869); Lesquereux (1884a); Abbott (1958).
(Figs. 2a–e)
22 DESCRIPTION: Ultimate axes apparently smooth, about 1 mm wide, with internodes 25 mm apart, bearing overlapping verticils with 14–16 isophyllous leaves, united at the base so as to form an annulus. Leaves oblong, tapering gradually in the upper quarter length into an acute, mucronate apex. Dimensions: 9–17 mm long and up to 2 mm broad; length/breadth ratio = 4.5–8.5. Vein straight and relatively broad, occupying about one fifth of the leaf width.
23 REMARKS: The holotype of Sternberg’s Annularia fertilis, a species often included in the synonymy of Annularia stellata (e.g., by Zeiller 1888; Crookall 1969), is from Westphalian strata at Königsgruben, Upper Silesia, Poland. This specimen, reproduced photographically by Kvaček and Straková (1997, pl. 23, fig. 1), shows verticils composed of 14–16 isophyllous leaves, 7 to 14 mm long, with acute, mucronate apices. Canadian specimens assigned to Annularia fertilis fit this species perfectly, in particular those figured here in Figs. 2a and 2e (the latter slightly deformed tectonically).
24 COMPARISONS: Annularia latifolia possesses shorter, oblanceolate leaves, with maximum width in the upper third; it has a smaller length/breadth ratio than Annularia fertilis. In addition, Annularia latifolia shows a tendency towards anisophylly; this is not apparent in the leaf verticils of the holotype of Annularia fertilis. The late Stephanian Annularia spinulosa has longer, anisophyllous, lanceolate leaves (at 27–45 mm length, more than double the length of those of Annularia fertilis), with the greatest width just above the middle, and a sharply pointed apex. Annularia spinulosa has also more leaves (16 to 32) per verticil. Annularia sphenophylloides has smaller leaves than Annularia fertilis, and these are in anisophyllous verticils. Also, the leaves of Annularia sphenophylloides are spatulate and possess a markedly swollen, rounded, mucronate apex that is quite distinctive. The leaves of Annularia asteropilosa are also lanceolate, but are narrower, with a greater length/breadth ratio, and thus have a less pointed apex, apparently without a mucron.
25 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: The holotype is from Westphalian strata of the Upper Silesian Basin, Poland. Gothan et al. (1959) recorded this species (misidentified as Annularia jongmansii) from Namurian C to Westphalian B of the Ruhr District, western Germany. Josten’s (1991) specimen originated from Westphalian A (Langsettian) strata of the Ruhr District. Purkyňová (1962) figured specimens from upper Namurian B (Marsdenian) to Westphalian A (Langsettian) in the Ostrava-Karviná coalfield (Czech part of the Upper Silesian Basin). Tenchov (1987) figured this species from the Mogilište Formation, of Westphalian B (Duckmantian) age, in Bulgaria. Annularia fertilis is rarely recorded, but occurs widely.
26 OCCURRENCE IN THE MARITIME PROVINCES: Saint John (New Brunswick): Bell (1944): locality 788 (three pieces without catalogue number — fragmentary); locality 1594 = 2577 (GSC 5766 — one specimen in the same rock sample as that figured in Bell 1944, pl. LXXVII, fig. 1 as Sporangites acuminata + nineteen specimens without GSC catalogue number — eighteen numbered as locality 2577 and one as 1594; see Figs. 2a, c–e). Fern Ledges (New Brunswick): New Brunswick Museum collection: NBMG 1757/1. McGill University Collection: n° 3348 + one piece without catalogue number. Sydney Basin (Nova Scotia): Zodrow and McCandlish (1980).
27 OCCURRENCE IN THE UNITED STATES: Indiana: Wood (1963). Michigan: Arnold (1949).
(Fig. 3)
Excludenda:
28 DESCRIPTION: Axes longitudinally striate, 0.5–0.75 mm wide, with internodes 10–15 mm apart. Verticils on ultimate branches spaced at a little more than leaf length or slightly touching. Verticils with 10–12 leaves of approximately equal length, free, straight, oblanceolate, with maximum width above the middle and tapering basally and apically; blunt, obtuse apex. Dimensions: 4–6 mm long at 0.8–1.5 mm broad; length/breadth ratio = 4–5. Central vein not visible.
29 REMARKS: Annularia galioides was ascribed to Asterophyllites by Lindley and Hutton (1832), and recorded from lower Duckmantian strata at Barnsley, Yorkshire, England. Kidston (1891) transferred this species to Annularia. Lesquereux’s Annularia cuspidata was placed in synonymy with Annularia galioides by Kidston (1893). Abbott (1958) did the same with Lesquereux’s Annularia emersonii.
30 Here, we synonymize Matthew’s Annularia latifolia var. minor with Annularia galioides. Matthew’s variety was considered by Bell (1944) to fit the range of leaf length of Annularia latifolia; however, the verticils of the latter are anisophyllous and its leaves are widest in their upper third.
31 COMPARISONS: Annularia sphenophylloides has anisophyllous verticils with a larger number of leaves (12 to 18) that are spatulate, with a distinct mucron on the rounded apex. Although its leaves are also oblanceolate, Annularia latifolia has anisophyllous verticils with a larger number of leaves (12 to 16) that are longer and show a greater length/breadth ratio. Annularia microphylla has a similar number of leaves per verticil, but these are sickleshaped and narrow gradually from a maximum width at mid-length to a pointed apex. Its leaves are of similar size to those of Annularia galioides, but have greater length/breadth ratio and are characterized by a rigid, slightly vaulted lamina. The upper Stephanian species Annularia spicata has smaller leaves (on average 2.5–3 mm long) that are stiffer, narrower, and have pointed apices.
32 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: The holotype of Annularia galioides is from lower Duckmantian strata at Barnsley, Yorkshire, England. Crookall (1969) recorded this species from Westphalian B to Westphalian D (Duckmantian to Asturian) in Britain. Leggewie and Schonefeld (1961) recorded it from Westphalian A and lower Westphalian B (Langsettian and lower Duckmantian) of the Ruhr District, western Germany. According to Josten (1991), the species ranges from Langsettian to Bolsovian.
33 OCCURRENCE IN THE MARITIME PROVINCES: Cumberland Basin (Nova Scotia): Bell (1944): locality 1073 (GSC 9594 + GSC 9595 + GSC 9596 + GSC 9597 + GSC 9598 + GSC 9600 + GSC 9601 + one specimen with rubbedout catalogue number — all specimens poorly preserved); locality 1088 (GSC 10995 + GSC 10996 — part and counterpart). Wilson Collection (GSC, Ottawa): locality 810 (two pieces without catalogue number). Fern Ledges (New Brunswick): Dawson (1868); Matthew (1906a); Bell (1944): locality 351 (one piece without catalogue number); Bell (1966): locality 804 (GSC 14916 — here Fig. 3).
34 OCCURRENCE IN THE UNITED STATES: Michigan: Arnold (1949). Missouri: Basson (1968). Ohio: Lesquereux (1881–1884a); Abbott (1958); Cross et al. (1996). West Virginia: Gillespie et al. (1966); Gillespie et al. (1978); Blake et al. (2002).
(Fig. 4; Figs. 5a–b)
35 DESCRIPTION: Ultimate axes up to 2.5 mm wide, with internodes 20–25 mm long, bearing slightly overlapping verticils. Verticils with 22–24 leaves, of unequal length, lying in the same plane as the axis and united at the base so as to form an annulus. Leaves oblanceolate, with convex margins and the greatest width in the upper third of leaf length; apex obtuse, with a mucron that is not always visible (frequently embedded in the matrix). Leaves are long and vary in size according to their position, the laterals (those placed perpendicular or subperpendicular to the axis) being longer than the lower and upper ones (more or less parallel to the axis); consequently, the verticils show an elliptical shape. Dimensions: varying between 20–25 mm and 30–45 mm length at 2.50–4.25 mm width; length/breadth ratio = 8–10. Vein clearly marked, straight, c. 0.3 mm wide.
36 REMARKS: Bell (1938) figured four specimens of this species from the Sydney Basin, Nova Scotia, as Annularia stellata forma mucronata. Two of these (Bell 1938, pl. XC, figs. 1–2) were included by Abbott (1958) in the synonymy of Annularia stellata; she attributed the other specimens (Bell 1938, pl. LXXXIX; pl. XCI, fig. 1) to Annularia mucronata. The holotype of the often-cited Annularia stellata (Schlotheim 1820, Taf. I, fig. 4 — possibly lost according to Kvaček and Straková 1997, p. 142) came from upper Stephanian strata of Kammerberg at Manebach, Thuringia, Germany. Barthel (2000) considered Annularia spinulosa (Sternberg 1821, Taf. 19, fig. 4 — photographically figured by Kvaček and Straková 1997, pl. 51, fig. 4, and Barthel 2000, Abb. 1a) as the correct name, with Annularia stellata as a synonym. Most authors now accept Barthel’s point of view.
37 Annularia mucronata is a species introduced by Schenk (1883) from Permian strata in China. It is characterized by verticils with relatively long, spatulate, mucronate leaves. Most of the upper Westphalian and Stephanian specimens identified as Annularia mucronata from North America (e.g., Abbott 1958; Wood 1963) may be assigned to Annularia sphenophylloides.
38 Most comparable to Annularia mucronata are the specimens described by Elias (1931) as Carpannularia, a genus based on the presence of some reproductive structures (which Elias assumed to be seeds) that are attached to Annularia-type verticils. Abbott (1958) accepted the connection between these "seeds" and the leaf verticils and synonymized Elias’s Carpannularia americana with Annularia stellata. However, Cridland (1968), who reexamined Elias’s specimens, noticed that the "seeds" are detached, and not connected to the Annularia verticils. He proposed the synonymy of Carpannularia americana with Annularia mucronata, noting a similar leaf size, spatulate shape and mucronate apices. He also regarded the leaves figured by Elias as completely covered with "hairs".
39 We agree with Abbott that more than one species is represented in Bell’s (1938) material, assigning two of Bell’s specimens (pl. LXXXIX; pl. XCI, fig. 1) to Annularia inflata. The specimen shown in Bell’s pl. XC, fig. 1 is here included in Annularia stopesiae sp. nov.; the fourth specimen can only be assigned as Annularia sp. indet.
40 Annularia inflata, a rarely recorded species, has been introduced by Lesquereux (1870) on the basis of two specimens from Mazon Creek, Illinois. Rather than providing a proper description, he noted the differences between his material and Annularia longifolia Brongniart. Lesquereux (1870) mentioned that Annularia inflata has oblanceolate, obtuse leaves with a subcylindrical or inflated shape and without a clearly marked vein. Annularia longifolia has flatter leaves with convex margins and a well marked vein. Lesquereux admitted the possibility that these two kinds of leaf might belong to a single species, and considered that the dimorphism might be due to some leaves being subaerial (corresponding to Annularia longifolia) and others aquatic (Annularia inflata). However, this is speculation. Janssen (1940, pl. I, fig. 1) published a photograph of Lesquereux’s holotype under the name Annularia stellata.
41 Annularia longifolia is an invalid name, introduced by Brongniart (1828a) without description or illustration. Brongniart (1828a, p. 153) noted only the differences in leaf length in a verticil, and (on p. 156) placed Casuarinites stellatus Schlotheim and Bornia stellata Sternberg in synonymy with Annularia longifolia.
42 COMPARISONS: Annularia spinulosa (= Annularia stellata) has 16 to 32 leaves per verticil with 25–45 mm length. As in Annularia inflata, the lateral leaves are longer than the lower and upper ones. Annularia spinulosa leaves are widest just above their middle, and the apices are bluntly pointed. Annularia stopesiae sp. nov. also displays anisophyllous verticils with similar number of leaves, but these are linear-lanceolate, much longer (up to 85 mm) and show a distinct cell pattern.
43 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: from Asturian strata of the Shelburn Formation, Indiana. Lesquereux’s (1870) type material as well as that figured Canright’s (1959) specimens are also from Indiana; these are by Noé (1925) and Darrah (1969) are from uppermost from the Lower Block Coal, lower Brazil Formation of late Asturian and/or lowermost Cantabrian strata at Mazon Bolsovian age according to Bashforth and Nelson (2015). Creek, Illinois, U.S.A. White (1880) figured material from Asturian strata of the Shelburn Formation, Indiana. Canright’s (1959) specimens are also from Indiana; these are from the Lower Block Coal, lower Brazil Formation of late Bolsovian age according to Bashforth and Nelson (2015).
44 OCCURRENCE IN THE MARITIME PROVINCES: New Brunswick Museum collection: NBMG 3423 (Saint John — specimen described and figured as Annularia longifolia mutation Leavittii in Matthew 1906a and 1906b — see Fig. 4) + NBMG 7649 (Sunbury County — together with Laveineopteris polymorpha and labelled as Annularia longifolia and Neuropteris sp.; here as Figs. 5a–b). Sydney Basin (nova scotia): Bell (1938): locality 513 (GSC 2269); locality 556 (GSC 3107). Bell (1966): locality 1331 (GSC 14906). Zodrow and McCandlish (1980).
45 OCCURRENCE IN THE UNITED STATES: Illinois: Lesquereux (1870), Noé (1925), Janssen (1940), Janssen (1957), Darrah (1969), Wittry (2006). Indiana: White (1880), Canright (1959). Missouri: Basson (1968). Ohio: Abbott (1958). West Virginia: Gillespie et al. (1978).
(Figs. 6a–b; Figs. 7a–k)
Excludenda:
46 DESCRIPTION: Ultimate axes longitudinally striate, 0.8–1 mm wide, with internodes 10–12 mm apart, bearing verticils that touch or slightly overlap when spread out on the bedding plane. Verticils anisophyllous to a varying extent, with lateral leaves longer than those parallel to the axis. There are 12 to 16 leaves in a verticil, united at the base to constitute an annulus, oblanceolate, with maximum width in the upper third and gradually tapering to an obtuse, mucronate apex. Dimensions: 8–12 mm long at 1.25–1.9 mm (maximum) width; length/breadth ratio ≈ 6. Vein straight, relatively broad, c. 0.6 mm. In well-preserved adpressions an elongate, relatively coarse epidermal cell pattern, slightly oblique to the vein, is apparent.
47 REMARKS: Asterophyllites latifolia was introduced by Dawson in 1862 and transferred to Annularia by Schimper (1869), who renamed it (illegitimately) Annularia dawsonii. Kidston (1886) proposed the combination Annularia latifolia. Stopes (1914), who (incorrectly in our view) synonymized Annularia latifolia with the Stephanian species Annularia stellata, figured photographically the reasonably well-preserved specimens illustrated by Dawson in 1871. Abbott (1958) provided outline diagrams as well as a description and a brief history of what she regarded as Annularia stellata (but referring to specimens that in our view belong to Annularia latifolia).
48 Bell (1944) retained both Annularia latifolia and Annularia stellata as separate species. The Canadian species, Annularia latifolia, is identical to Annularia jongmansii, a species introduced and described more fully by Walton (1936) from lower Westphalian strata of the Midland Valley of Scotland. He seems to have been unaware of Annularia latifolia. Annularia jongmansii is characterized by anisophyllous verticils with lanceolate leaves showing a subrounded apex that includes a tiny mucron. Walton (1936) emphasized the presence of a relatively coarse, elongate epidermal cell pattern, which is also apparent in Annularia latifolia (Fig. 7k). These two species are identical in all respects and thus synonymous.
49 Bell (1944, p. 100) discussed Annularia latifolia, but did not provide an illustration. Practically all the localities cited by Bell (1944) are in New Brunswick, the only exception being locality 1362 at Joggins, Nova Scotia. However, the corresponding specimens (without catalogue number) are assigned here to Annularia microphylla. We note also that the specimen from New Brunswick figured by Bell (1966, pl. VII, fig. 3) as Annularia latifolia belongs to Annularia galioides (see Fig. 3).
50 COMPARISONS: Annularia sphenophylloides also has leaves with a prominent mucron, but these leaves are smaller, up to 12 mm long (6 to 8 mm on the average), spatulate and widest at the apex. Annularia galioides also has oblanceolate leaves, but these are smaller, up to 6 mm long, and have a smaller length/breadth ratio. In addition, leaves of Annularia galioides are of near-equal length in almost isophyllous verticils. Annularia microphylla has verticils with lanceolate and sickle-shaped leaves of equal length and stiffer aspect.
51 The leaves in Annularia microphylla are shorter than those of Annularia latifolia and have a smaller length/breadth ratio. Verticils of Annularia fertilis have isophyllous leaf whorls, with oblong, longer leaves, with a greater length/breadth ratio. Leaves of Annularia asteropilosa are less pointed and have a greater length/breadth ratio.
52 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: The synonymous Annularia jongmansii has been reported in Europe from upper Langsettian to lower Asturian strata. Walton’s type is from lower Westphalian strata in Clackmannanshire, Scotland. Kidston’s (1914) specimen (which he determined as Annularia stellata) is from upper Duckmantian strata of Staffordshire, England. Jongmans and Kukuk (1913) recorded material from Asturian sediments at Piesberg, western Germany. Kotasowa (1968) documented the species (as Annularia radiata) from Westphalian A (Langsettian) in the northeastern part of the Upper Silesian Coal Basin, Poland. Tenchov’s (1987) material came from several horizons in Westphalian A, B and C (Langsettian, Duckmantian and Bolsovian) strata from the Dobrudža Basin, Bulgaria. Wagner and Álvarez-Vázquez (2010) recorded Annularia jongmansii from the upper Langsettian and the lower Bolsovian in the Peñarroya Basin, southwestern Spain, and from lower Asturian strata of the Sierra de la Demanda, Burgos province, northern Spain.
53 OCCURRENCE IN THE MARITIME PROVINCES: Saint John (New Brunswick): Dawson (1862), Dawson (1868), Dawson (1871), Stopes (1914), Bell (1944), Abbott (1958), Falcon-Lang and Miller (2007). Wilson collection (Geological Survey Canada, Ottawa): locality 136 (136B); locality 139 (139 — together with Calamites sp. + 139a — here Figs. 7f and Figs. 7g–h + 139b + 139c + 139d); locality 810 (three pieces without catalogue number — here Figs. 7a–c; together with Annularia galioides); locality 828 (198b — here Figs. 7i–k); locality 2254 (one piece without catalogue number).

54 OCCURRENCE IN THE UNITED STATES: Illinois: Janssen (1957). Michigan: Arnold (1934). Ohio: Abbott (1958). Pennsylvania: Lesquereux (1884a), Wittry (2006). West Virginia: Jongmans (1937).
(Fig. 8)
55 DESCRIPTION: Ultimate axis c. 0.75 mm wide, with internodes 4.5–5 mm long bearing verticils that touch or slightly overlap. Verticils with 12 leaves of equal length, lanceolate and sickle-shaped, gradually narrowing from maximum width at the middle to a pointed apex. Lamina relatively thick, slightly vaulted. Dimensions: 5–6 mm long at 0.5–0.6 mm width; length/breadth ratio = 10. Vein straight, immersed in the lamina, and occupying one third of leaf width.
56 REMARKS: The description given here is based on a single specimen from Joggins, Nova Scotia. It was not described by Bell, although part of his 1911 collection. Even though fragmentary (only 30 mm), it shows the sickle-shaped leaves, with a thick, vaulted lamina that is characteristic of Annularia microphylla. This species has often been regarded as conspecific with either Annularia galioides (e.g., Kidston 1891; Jongmans 1911) or Annularia spicata (Potonié 1893), but these three species can be differentiated without too much difficulty (see under Comparison) and have quite different ranges.
57 We regard Asterophyllites vernensis, described by Arnold (1949) from Grand Ledge, Michigan, as a synonym of Annularia microphylla. Arnold pointed out that the leaves of Asterophyllites vernensis are curved and laterally imprinted, as in Asterophyllites. Indeed, he compared Asterophyllites vernensis with Asterophyllites grandis, noting broader leaves in Asterophyllites vernensis. Arnold’s species was transferred to Annularia by Abbott (1958). Although Abbott maintained Annularia vernensis as a separate species, she noted its close resemblance to Annularia galioides.
58 COMPARISONS: Annularia microphylla is distinctive, easily identified by its leaf shape and a thick lamina. It shows a superficial resemblance to Annularia galioides, but the oblanceolate leaves of the latter are flat and straight.
59 Annularia spicata has smaller, oblong leaves, with pointed apices; there are also fewer leaves per verticil in Annularia spicata.
60 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Annularia microphylla is rarely cited. The holotype is from the lower Westphalian of Belgium. Kidston (1914) and Crookall (1969) recorded this species from the Westphalian A and lower Westphalian B (Langsettian and lower Duckmantian) in Britain. Gothan and Remy (1957), Gothan et al. (1959), Leggewie and Schonefeld (1961), and Josten (1991) record the same range for this species from the Ruhr District, western Germany. García-Loygorri and Ortuño Aznar (1969) figured Annularia microphylla from Langsettian strata of the Villanueva del Río y Minas coalfield, Sevilla province, southwestern Spain.
61 OCCURRENCE IN THE MARITIME PROVINCES: Cumberland Basin (Nova Scotia): Bell’s collection 1911: locality 1362 (one piece without catalogue number).
62 OCCURRENCE IN THE UNITED STATES: Michigan: Arnold (1949); Abbott (1958). West Virginia: Gillespie et al. (1978).

Excludenda:
63 DESCRIPTION: Ultimate axes longitudinally striate, 1–2 mm wide, with internodes 9–14 mm apart bearing verticils flattened in the same plane as the axis, each with 10–14 leaves that overlap slightly. Leaves linear, narrow, of uniform size, with 20–25 mm long (incomplete) at 0.4–0.5 mm width; length/breadth ratio ≈ 50. Lamina thick, vaulted. No vein. visible.
64 COMPARISONS: Annularia radiata has shorter, linearlanceolate leaves with a smaller length/breadth ratio than those of Annularia pseudostellata. Annularia stopesiae sp. nov. is anisophyllous, with longer lateral leaves. This species also has more leaves in a verticil (20–24); these are longer and wider than those of Annularia pseudostellata.
65 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Annularia pseudostellata has been rarely recorded, but is apparently widespread. It occurs in lower Bolsovian to Asturian strata.

67 OCCURRENCE IN THE UNITED STATES: Michigan: Arnold (1934).
(Figs. 9c; Fig. 10)
Excludenda (including Annularia acicularis):
68 DESCRIPTION: Ultimate axes longitudinally striate, c. 1–1.5 mm wide, with internodes 10–25 mm apart bearing verticils spread out on the bedding plane that touch but do not overlap. Verticils with 12 to 16 leaves, narrowly joint at the base, of almost equal length, linearlanceolate, broadest about the middle and tapering to an acute apex. Dimensions: 11–24 mm long at 1–1.5 mm width; length/breadth ratio = 11–16. A longitudinal cell pattern is observed in some well-preserved leaves.
69 REMARKS: Annularia acicularis, here included in Annularia radiata, was introduced by Dawson (1862) as Asterophyllites acicularis; it was transferred to Annularia by White (1900). Bell (1944, p. 101) included Annularia acicularis in the synonymy of Asterophyllites lentus Dawson, a species that Stopes (1914, p. 20) regarded as a probable synonym of Annularia radiata. Abbott (1958) distinguished Annularia acicularis from Annularia radiata by the presence of linear leaves in Annularia acicularis, as against the linear-lanceolate leaves and a greater length/breadth ratio for Annularia radiata. She also noted that Annularia acicularis has anisophyllous leaf verticils, in contrast to the isophyllous verticils of Annularia radiata. However, these distinctions are blurred when Brongniart’s and Dawson’s original drawings are compared. Annularia acicularis has been ignored by European authors.
70 Most of the specimens that Bell (1944) assigned to Annularia acicularis have been available for reexamination. Six of these specimens (Bell 1944, pl. LVIII, fig. 5; pl. LX, fig. 6; pl. LXIII, fig. 3; pl. LXIV, fig. 5; pl. LXV, fig. 2; pl. LXIX, fig. 5) are included here in Annularia radiata. Another specimen (Bell 1944, pl. LVIII, fig. 2) represents a node of Calamites with stem leaves and thus cannot be assigned to Annularia. The specimen figured as Asterophyllites sp. (= Annularia radiata?) by Stopes (1914, pl. IV, fig. 5), after Dawson (1871), probably belongs also to Annularia radiata, but is too poorly preserved for a definitive identification. A specimen figured as Asterophyllites acicularis (= Asterophyllites equisetiformis?) by Stopes (1914, pl. IV, fig. 6), after Dawson (1871), is here assigned to Asterophyllites grandis.
71 COMPARISONS: Annularia fertilis possesses isophyllous verticils with a similar number of leaves to that in Annularia radiata; however, these are oblong, with an acute, mucronate apex. They are also a little longer, and possess a smaller length/breadth ratio. Annularia latifolia has anisophyllous leaf verticils with smaller, oblanceolate leaves topped by an obtuse, mucronate apex. Its leaves are smaller, with a smaller length/breadth ratio. In well-preserved adpressions of this species, the presence of an elongate, relatively coarse epidermal cell pattern, slightly oblique to the vein, is distinctive. Annularia fimbriata has more leaves in a verticil (15 to 20) than does Annularia radiata. The leaves are shorter and have a smaller length/breadth ratio. A transfer preparation by Walton (1936) shows a shallow median groove extending from the leaf base up to near the sharply pointed apex; he also recorded slightly oblique rows of hairs. Annularia ramosa has fewer leaves in a verticil (8 to 12) than Annularia radiata; they are also shorter and have a smaller length/breadth ratio. Annularia isperichii, described by Tenchov (1987), has fewer leaves (9 to 12) per verticil; they are of similar size to those of Annularia radiata, but are more markedly lanceolate, with a pointed, mucronate apex.
72 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Annularia radiata occurs most commonly in upper Langsettian and Duckmantian strata. Although the provenance of the holotype is unknown (Brongniart 1822), that of Asterophyllites foliosa, a synonym, is from the lower Duckmantian Bensham coal seam, Jarrow Colliery, near Newcastle, northern England. Annularia asterophylloides, another synonym, came from an unknown horizon in the lower Westphalian of Belgium (Sauveur 1848). Josten (1991) recorded Annularia radiata as ranging throughout Westphalian A–C (Langsettian to Bolsovian), and disappearing in the lower Westphalian D (Asturian). Tenchov (1987) figured this species from Westphalian B (Duckmantian) strata in Bulgaria. Wagner and Álvarez-Vázquez (2010) recorded Annularia radiata from Langsettian to lower Asturian strata in the Iberian Peninsula.

(Fig. 9b)
Excludenda:
75 DESCRIPTION. Penultimate axes straight, 2–2.25 mm wide. Ultimate axes oppositely inserted at right angles, c. 0.5–0.75 mm wide; internodes 20 mm apart, bearing verticils with 8 to 12, widely spaced leaves all of similar length, linear-lanceolate, widely attached at the base and slightly pointed. Dimensions: 3.5–8 mm long at 0.15–0.3 mm wide; length/breadth ratio = 23–26. Vein not visible, obscured by a longitudinal cell pattern.
76 REMARKS: Bell (1944) included in Annularia aculeata specimens with verticils showing considerable variation in the number, size and shape of leaves. The holotype (Bell 1944, pl. LXVIII, fig. 4) shows second order branches with two fragmentary first order branches and one incomplete verticil that may be identified (a second is too poorly preserved), with 8 leaves, 3.5–4 mm long (three of these leaves show only the insertion). This specimen is a compression well enough preserved to show a longitudinal cell pattern. Very similar to the holotype is a well-preserved specimen from a locality (1420) in Inverness County, Cape Breton Island, Nova Scotia, showing widely spaced, small, slender, pointed leaves, fused at the base (Bell 1944, pl. LX, figs. 3–4; our Fig. 9b), all characters that accord with Annularia ramosa.
77 Several authors (e.g., Jongmans 1911; Abbott 1958; and Crookall 1969) regarded Annularia ramosa as a synonym of Annularia radiata. However, the holotype of Annularia radiata has a greater number of leaves per verticil (up to 16) than is the case for Annularia ramosa; they are also longer (20–22 mm), with a greater length/breadth ratio. These two species are clearly different.
78 COMPARISONS: Annularia galioides possesses oblanceolate leaves with an obtuse apex; maximum width occurs just above the middle, in contrast to the linearlanceolate, fleshier leaves with pointed apices of Annularia ramosa. Annularia radiata has more leaves per verticil (12–16); although these leaves, like those of Annularia ramosa, are linear-lanceolate and in isophyllous verticils, they are longer. Annularia asteris has stiff, narrow leaves with acuminate apices; verticils are smaller (2–4.5 mm long and 0.20–0.25 mm width) than those of Annularia ramosa. Although Annularia microphylla has leaves similar in shape to those of Annularia ramosa, they are stiffer and curved, favouring adpression parallel to the axis.
79 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Annularia ramosa is fairly widespread and ranges from Namurian B to lower Bolsovian. The type material (Weiss 1884) is from lower Westphalian strata in Neurode (Nowa Ruda), Lower Silesia, Intrasudetic Basin, southwestern Poland. Josten (1991) records this species (as Annularia ramosa and Annularia aculeata) from upper Langsettian and lower Duckmantian strata in the Ruhr District in western Germany. Specimens figured by Tenchov (1978) from Bulgaria as Annularia asteris and Annularia radiata are from Namurian C (Yeadonian) and Westphalian A (Langsettian) strata. Stockmans and Willière (1965) recorded Annularia ramosa from Langsettian deposits at San Emiliano, León province, northwestern Spain. Wagner and Álvarez-Vázquez (2010) added a record from the Langsettian of La Camocha coal mine, near Gijón (Asturias province), northwestern Spain; they also recorded this species from upper Langsettian and lower Bolsovian strata of the Peñarroya Basin (Córdoba province), southwestern Spain.
80 OCCURRENCE IN THE MARITIME PROVINCES: Cumberland Basin (Nova Scotia): Bell (1944): locality 162 (nine pieces without catalogue number); locality 999 (GSC 9578 + GSC 9579 — both poorly preserved); locality 1080 (two pieces without catalogue number); locality 1406 (GSC 9318 — with doubt + GSC 9321 + GSC 9324 + four pieces without catalogue number — together with Karinopteris acuta and Asterophyllites sp. indet.); locality 1412 (GSC 9325 — holotype of Annularia aculeata); locality 1420 (GSC 9322 — here refigured, as part, in Fig. 9b); locality 1435 = 1406 (four pieces without catalogue number — together with Alethopteris decurrens and Bergeria dilatata); locality 1728 (cf. — four pieces without catalogue numbers). Minto coalfield (New Brunswick): Bell (1962): locality 1000 (GSC 837).
81 OCCURRENCE IN THE UNITED STATES: Alabama: Gillespie and Rheams (1985); Lyons et al. (1985). Georgia: Gillespie and Crawford (1985). Missouri: Basson (1968). West Virginia: Jongmans (1937); Gillespie et al. (1966); Gillespie et al. (1978).
(Figs. 11–12)
82 HOLOTYPE: GSC 9876, a specimen described and figured by Bell 1944 (pl. LXX, fig. 5) as Annularia stellata forma longifolia (Fig. 11 of the present paper).
83 DERIVATION OF NAME: Named after Marie C. Stopes in recognition of her significant contribution to Canadian palaeobotany through her work at Fern Ledges, Saint John.
84 TYPE LOCALITY AND HORIZON: Mapleton Brook, Springhill area, 300 feet below driving dam (GSC locality 3116).
85 DIAGNOSIS: Anisophyllous verticils flattened in spread out condition; 20–24 linear-lanceolate leaves, up to 85 mm long and 1.5–2 mm broad. Vein straight, broad and well marked.
86 DESCRIPTION: Ultimate axes 2–5 mm wide, with internodes 16–45 mm apart bearing slightly overlapping verticils which are flattened in spread-out condition; anisophyllous (slightly elliptical), with the lateral leaves longer than those situated in lower and upper parts. Each verticil consists of 20–24 large, linear-lanceolate leaves, united at the base so as to form an annulus. Dimensions: 40 (incomplete) – 85 mm length at 1.5–2 mm width; length/breadth ratio = 50–56. Vein straight, broad and well marked in the central part of a thick leaf lamina.
87 REMARKS: Bell (1944, pl. LXX, fig. 5; 1966, pl. X, fig. 4) figured two specimens of Annularia with very long, thin leaves, more than 20 per verticil, from two different localities at Springhill, Cumberland Basin, Nova Scotia. Bell (1944, p. 102) also recorded another (unfigured) specimen, from the Joggins section. All these specimens are preserved in a similar lithology. Bell applied the name Annularia stellata forma longifolia. However, this is based on the invalid species name Annularia longifolia (see Remarks on Annularia inflata). Leaf size in Bell’s specimens is comparable to that known for Annularia inflata, but its leaves are narrower and linear-lanceolate. Bell (1944) observed a transverse epidermal cell pattern that he described as "… short hair-like fibres that run generally transverse to the midrib…"; this is characteristic for Annularia spinulosa (= Annularia stellata).
88 Specimens similar to those recorded by Bell from Canada, also showing the transverse epidermal cell pattern, have been recovered from five different localities in lower Bolsovian strata at the eastern end of the Peñarroya–Belmez–Espiel coalfield, southwestern Spain (Álvarez-Vázquez 1995, pp. 270–271, lám. 90, figs. 1–2, labelled Annularia cf. stellata).
89 COMPARISONS: Annularia inflata has shorter and broader oblanceolate leaves with an obtuse apex. Length/breadth ratio is much lower, between 8–10. Annularia spinulosa also possesses slightly anisophyllous verticils with a similar number of leaves, but these are shorter (around 30 mm), lanceolate, with bluntly pointed apices; length/breadth ratio is lower. Asterophyllites longifolius has a similar number of long, narrow leaves, but these are shorter and joined in isophyllous verticils. In addition, Asterophyllites longifolius leaves are normally flattened sideways, close to the axis, at an angle of less than 45°.
90 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Spanish material included in the synonymy comes from lower Bolsovian strata of the Peñarroya–Belmez–Espiel coalfield, Córdoba province, southwestern Spain.
91 OCCURRENCE IN THE MARITIME PROVINCES: Cumberland Basin (Nova Scotia): Bell (1944): locality 3116 (GSC 9876 — holotype; refigured in Fig. 11). Bell (1966): locality 3110 (GSC 14910 — Fig. 12 + one piece without catalogue number). Minto coalfield (New Brunswick): Bell (1966): locality 1172 (GSC 14908 — with doubt).
92 OCCURRENCE IN THE UNITED STATES: Michigan: Arnold (1949). West Virginia: Gillespie et al. (1978).
93 TYPE: Asterophyllites radiatus Brongniart (= Annularia radiata Brongniart).
(Fig. 13)
Excludenda:
94 DESCRIPTION: Penultimate axes striate longitudinally (not always discernible), c. 1 mm wide; internodes 7–12 mm long, showing two oppositely inserted, small (10–20 mm long), smooth ultimate branches, with internodes 2–3 mm long.Verticils composed of up to 10 acicular leaves, as long as or slightly longer than the internodes, attached at right angles and reflexed sharply upwards to a position parallel to the next internode, with the acute apex often incurved towards the axis. Dimensions: 2–3 mm long and 0.2–0.3 mm wide at the base; length/breadth ratio = 10.
95 REMARKS: Bell (1944, pl. LXIII, fig. 2; pl. LXVIII, fig. 1) figured two distinctive specimens of Asterophyllites charaeformis. We also include in this species two specimens described by Bell (1944) as Annularia aculeata (Bell 1944, pl. LXII, fig. 2; pl. LXIII, fig. 4). An incomplete strobilus was figured as Calamostachys charaeformis by Bell (1944, pl. LXX, fig. 1).
96 The vegetative leaves of Calamostachys charaeformis are distinctive. Two specimens that Bell (1944, pl. LXVII, fig. 5; pl. LXXIV, fig. 5) identified as "Calamostachys of Asterophyllites grandis", are included here in Calamostachys charaeformis; also the specimens figured by Bell (1944, pl. LXXIV, figs. 4, 7) as "Calamostachys of Annularia aculeata". We also include in Calamostachys charaeformis the specimen figured by Stopes (1914, pl. III, fig. 4) as Calamostachys sp.
97 COMPARISONS: The hooked shape of leaves of Asterophyllites charaeformis is distinctive. The slightly larger, sickle-shaped leaves of Asterophyllites grandis distinguish that species from Asterophyllites charaeformis. The same difference in bract shape separates Calamostachys charaeformis and Calamostachys grandis. Asterophyllites lycopodioides has 4–6 acicular leaves of similar size, but these are closely adpressed to the axis and only slightly curved. In addition, each verticil reaches the next one.
98 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Asterophyllites charaeformis is a fairly common species. In Europe, it occurs usually in lower Langsettian to upper Bolsovian strata, but Kotasowa (1968) also recorded (but did not illustrate) it from the upper Namurian (Yeadonian) of the Upper Silesian Basin. The type material is from the Bolsovian strata of the Radnice Member, Kladno Formation, Bohemia, Czech Republic.
99 OCCURRENCE IN THE MARITIME PROVINCES: Cumberland Basin (Nova Scotia): Bell (1944): locality 162 (three pieces without catalogue number); locality 881 (GSC 5984 — Calamostachys charaeformis); locality 1070 (GSC 10187 + GSC 10185); locality 1086 (GSC 9994 — together with Sphenophyllum cuneifolium and Karinopteris acuta); locality 1125 (one piece without catalogue number); locality 1190 (GSC 9019); locality 1374 (GSC 10990 — with cf.); locality 1686 (GSC 8238); locality 2253 = locality 1386 (one piece without catalogue number — together with Laveineopteris polymorpha); locality 3995 (two pieces without catalogue number). Albert County (New Brunswick): Bell (1944): locality 621 (GSC 8565 — Calamostachys charaeformis + GSC 9135); locality 647 (GSC 10869 — Calamostachys charaeformis).

(Fig. 14)
Excludenda:
101 DESCRIPTION: Ultimate axis 0.30–0.50 mm wide, longitudinally striate, with internodes 2.5–4 mm long that become shorter and thinner towards the apex. Leaves slightly shorter than the internodes, thread-like, inserted at acute angles and curving slightly towards the axis in the upper half. Dimensions: 4–6 mm long and 0.3–0.4 mm broad; length/breadth ratio = 13–15. Vein not visible.
102 REMARKS: Bell (1944) figured two specimens of Asterophyllites grandis that are easily recognized by their sickle-shaped leaves, which overlap slightly at successive whorls. Bell also attributed four specimens of Calamostachys to Asterophyllites grandis, two of which are reassigned here to Calamostachys charaeformis. The cylindrical strobili of Asterophyllites grandis possess bracts similar to the vegetative leaves, and sporangiophores situated at about middle distance between verticils.
103 The similar species Asterophyllites tayloriorum, described from South Wales, is indistinguishable from Asterophyllites grandis in the vegetative state, but differs with regard to its associated fertile remains, assigned to Palaeostachyawagneri (Cleal and Shute 2016).
104 COMPARISONS: Asterophyllites charaeformis has smaller, distinctively reflexed leaves placed at right angles. Leaves of Asterophyllites lycopodioides are less curved and pass beyond the internode to touch the base of the next verticil.
105 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Asterophyllites grandis occurs in Yeadonian to upper Bolsovian strata. Type material of Bechera grandis and Bechera delicatula are both from Bolsovian strata of the Radnice Member, Kladno Formation, Bohemia, Czech Republic.

Excludenda:
108 LECTOTYPE (DESIGNATED HEREIN): The specimen fig-ured by Lindley and Hutton (1835, pl. 191) as Hippurites longifolia. Lindley and Hutton’s drawing is refigured here as Fig. 15.
109 DESCRIPTION: Ultimate axes with fine longitudinal striae, straight, 1–1.5 mm wide, with internodes 5–10 mm long, becoming shorter and narrower upwards. Verticils with up to 16 closely placed, linear-lanceolate leaves, showing nearly parallel margins and an acute apex; lower leaves attached at approximate right angles and curved at about mid-length; higher leaves are more or less straight and attached at acute angles. Dimensions; 10–14 mm long and 0.5–0.75 mm broad; length/breadth ratio = 18–20.
110 REMARKS: The (missing) type material of Schlotheim’s Asterophyllites equisetiformis (originally Casuarinites equisetiformis) originated from upper Stephanian strata of Wettin and Manebach, eastern Germany. Most authors acknowledge that a varied group of similar taxa has been figured under this name in the literature. Jongmans and Kukuk (1913) recorded as Asterophyllites equisetiformis forma schlotheimii the form introduced by Schlotheim (1820) for uppermost Stephanian (lower Permian?) material characterized by leaves that are relatively broad, are broadest at about one third above the base, and possess a sharply pointed apex. The taxon with more thread-like, narrow and parallel-sided leaves that occurs throughout the Westphalian Stage (up to the lower Asturian) was named Asterophyllites equisetiformis forma jongmansii by Josten (1991), who applied the name Asterophyllites equisetiformis forma equisetiformis to the Stephanian (including the upper Asturian) taxon. Josten’s Asterophyllites equisetiformis forma jongmansii includes both Asterophyllites equisetiformis forma typica of Jongmans (1914b) and Asterophyllites gothanii (Leggewie and Schonefeld in Gothan et al. 1959); both were poorly defined and inadequately figured. The fragmentary Canadian specimens do not warrant a detailed discussion. Lindley and Hutton’s specimen (lectotype) still needs to be reproduced photographically; however, we suggest for the time being that most of the Westphalian specimens recorded in the literature as Asterophyllites equisetiformis may be attributable to Asterophyllites lindleyanus.
111 Bell (1944) reported Asterophyllites equisetiformis as uncommon in the Cumberland Basin. Bell’s specimens (plus additional ones from the same localities) have been available for reexamination. His pl. LXX, fig. 2, representing only a fragment of leaf verticil, and pl. LXXI, fig. 3 (our Fig. 16c), which is a more complete specimen with several ultimate axes showing thin-leaved verticils, fit Josten’s Asterophyllites equisetiformis forma jongmansii, from the Westphalian. Bell’s pl. LXXI, fig. 1 (our Fig. 17) represents the swollen tip of a branch that may be interpreted as a response to a fungal infection, and attributed to Acrobulbillites (as described by Amerom 1973).
112 COMPARISONS: Asterophyllites equisetiformis, as found in the higher Stephanian, shows broader leaves with the maximum width at about one third from the base, and a sharply pointed apex. Leaves of Asterophyllites grandis are smaller, more falcate, and less broad than those of Asterophyllites lindleyanus, with a smaller length/breadth ratio. Leaves of Asterophyllites lycopodioides are shorter and less arched; they pass beyond the node above to touch the base of the next verticil.
113 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: The species occurs rarely in the Yeadonian, but is relatively common and widespread in Westphalian strata (up to and including the lower Asturian).

(Figs. 18, 19)
Excludenda:
116 DESCRIPTION: Ultimate axis 3–4 mm wide, with ribbed internodes 8–14 mm long. Verticils with up to 20 filiform leaves with acute apices, adpressed in the axial plane, inserted at an acute angle (30–45°), and overlapping 2–4 internodes. Dimensions: 25–40 mm long and ~ 1 mm width. Vein not visible.
117 REMARKS: Although Bell (1944) did not report Asterophyllites longifolius, he figured a moderately well-preserved specimen of Palaeostachya striata (Bell 1944, pl. LXXIII, fig. 6) from the Springhill area, Nova Scotia. Palaeostachya striata, a species that we consider synonymous with Palaeostachya elongata, is often regarded as the strobilus of Asterophyllites longifolius.
118 COMPARISONS: Asterophyllites longifolius is easily recognized by its long, filiform leaves that overlap several verticils.
119 STRATIGRAPHIC AND GEOGRAPHIC DISTRIBUTION: Asterophyllites longifolius is a long-ranging species, from upper Namurian to the lower Stephanian. The holotype is from Westphalian strata at Eschweiler, Aachen coalfield, western Germany. The holotype of its synonym, Asterophyllites rigidus, is from Bolsovian strata of the Radnice beds, Bohemia, Czech Republic. Sauveur’s Asterophyllites elegans, another synonym, came from the lower Westphalian of Belgium. Leggewie and Schonefeld’s Asterophyllites discifer, also a synonym, came from the Westphalian A (Langsettian) of the Ruhr District, western Germany. Crookall (1969) mentioned that Asterophyllites longifolius is fairly rare, occurring in Langsettian to Bolsovian strata in Great Britain.

122 We have updated the taxonomy of Annularia and Asterophyllites species from lower Westphalian strata of the Maritime Provinces after re-examination of material in the Geological Survey of Canada (GSC) collections in Ottawa, and in the New Brunswick Museum (NBMG) at Saint John.
123 As with the lycopsid taxa revised in an earlier paper (Álvarez-Vázquez and Wagner 2014), the published record of Canadian sphenopsids from lower Westphalian strata is only sporadic and may be regarded as incomplete. Further collecting might well increase the number of species recognized, but our current revision shows already that the species composition of Annularia and Asterophyllites in the Maritime Provinces is identical to that found in western Europe. Both areas obviously represent a single palaeogeographic region.
124 The profusion of names used by Dawson, Matthew and Bell needed to be scaled down considerably. We have reduced the number of species from 19 to 6. The following taxa have been maintained: Annularia asteris, Annularia latifolia, Annularia radiata, Asterophyllites charaeformis, Asterophyllites grandis and Asterophyllites longifolius. We have introduced one new species, Annularia stopesiae, based on Canadian specimens but including also material from western Europe that was attributed originally to Annularia stellata. Lesquereux’s Annularia inflata is reinstated herein. We make the case for using Göppert’s specific name Asterophyllites lindleyanus for Westphalian material commonly referred to as Asterophyllites equisetiformis and, more particularly, as Asterophyllites equisetiformis forma jongmansii.
125 The parameters used for species discrimination are set out in Tables 1 and 2, for Annularia and Asterophyllites, respectively. Table 3 shows the identifications accepted in the present paper, as compared with those made by Dawson (1862, 1868, 1871), Matthew (1906a, b) and Bell (1944, 1966).
We express our gratitude to John Utting for providing the stimulus for a general revision of lower Westphalian floras in the Maritime Provinces, and accompanying the second author on several visits for which he provided logistic support. Jean Dougherty was most helpful in providing access to material and data regarding the fossil collections of the Geological Survey of Canada in Ottawa. Randall Miller did the same in the New Brunswick Museum at Saint John, providing geological information. Robert Wagner gratefully acknowledges a G.F. Matthew Grant from the New Brunswick Museum. Access to the Dawson Collection at the Redpath Museum, McGill’s University, Montreal is also acknowledged. The paper benefited from constructive comments and suggestions by Arden Bashforth and Chris Cleal. Various suggestions by the Editor, Rob Fensome have been well received.
