Abstract
Two types of leaves were observed in Komlopteris nordenskioeldii (Nath orst) Barbacka and Ctenozamites cycadea (Berger) Schenk. The differenc es relate both to morphological and cuticular features and correspond with characters of sun and shade leaves in Angiosperms. This feature i s discussed for the first time in Pteridosperms. (C) 1998 Elsevier Sci ence B.V. All rights reserved.
