The Botanical Review, 1999
A survey of Cycadalean taxa of Argentina (including Antarctica) is presented. The record of leaves represented byNilssonia, Pseudoctenis, Ctenis, Mesodescolea, Ticoa, Almargemia,Kurtziana, andZamia genera are summarized. Recent investigations made of cuticles with transmission and scanning electron microscopy are included. In stems, a preliminary study

Biochemical Systematics and Ecology, 1975
Abstract Biflavanoid patterns of leaves of 82 species of the order Cycadales comprising 3 families and 10 genera have been determined. The biflavanoids were identified by TLC, UV, NMR and MS studies. Pattern differences between species, when detected, involve the position or degree of methylation of the base compounds.
