Abstract
Historically collected specimens of the Pennsylvanian pteridosperm Eremopteris artemisiaefolia have been reinvestigated to provide detailed information on its morphology and cuticular anatomy and to enable some of the external features of the plant to be reconstructed. The stem bore a distal crown of helically arranged compound leaves that show evidence they were actively abscissed from the plant. The blade consists of a main rachis that is straight or curved and may be undivided or show a single overtopped or occasionally dichotomous division. Secondary foliar segments are once or twice divided, with ultimate segments consisting of an elongate lanceolate blade, sometimes with one or two pairs of suboppositely arranged basal lobes or subsegments. Dense parallel veins run along the ultimate segments and only rarely fork. Stomata occur on both surfaces of the blade but more densely on the abaxial surface; papillae surrounded the abaxial stomata but not the adaxial ones. Remains of platyspermic bicornute ovu...
