Abstract

Macroneuropteris scheuchzeri has been extensively figured and called by many different names, particularly in the European literature, since the species was erected in 1699. Much of the nature of this arborescent-medullosalean tree still remains to be documented, i.e., fructification, trunk, root, and frond architecture, but its heterophyllous foliage is well known. Based on the large macrofossil collections from the Pennsylvanian Sydney Coalfield, Nova Scotia, Canada, it is possible to present an overall view of the diverse foliar nature of this remarkable medullosalean tree. Suggestions are offered as to how the many foliar forms fit into the bipinnate frond of Laveine and Brousmiche (1982). RÉSUMÉ Le Macroneuropteris scheuchzeri a été abondamment décrit et a été appelé de nombreux noms différents, en particulier dans la documentation européenne, car l'espèce a été établie en 1699. Il reste encore à documenter une vaste part de la nature de cet arbre arborescent-médullosaléen, c.-à-d. la fructification, le tronc, les racines et l'architecture des frondes, mais on connaît bien son feuillage héterophylle. Il est possible, en se basant sur les grandes collections de macrofossiles du terrain houiller pennsylvanien de Sydney, Nouvelle-Écosse, Canada, de présenter un aperçu de la nature foliaire diversifiée de ce remarquable arbre médullosaléen. Des hypothèses sont avancées sur la façon dont les nombreuses formes foliaires s'insèrent dans la fronde bipennée de Laveine et Brousmiche (1982).
