Etymology:
Cycadis, a Latinised form of Cycas, with the Latin
folius, leaf, in reference to the Cycas-like leaves.

Vernacular:
Historical notes:
Described as a species of Zamia in 1801 by French botanist
--
Jaquin.
Distinguishing features:
The narrow entire leaflets are distincive, but can be confused with E.
ghellinckii and E. friderici-guilielmi. E. ghellinckii
usually has even narrower leaflets that can be distinguished by the recurved
margins. E. cycadifolius can be separated from E. friderici
guilielmi by erect crown of stiff leaves with usually shorter and
narrower leaflets, and the absence of thick wool from the crown. Stems are
also shorter, and cones fewer in number.
Distribution and habitat:
Widespread in eastern Cape Province, in grassland on shallow soils over
shale mountain slopes.
Conservation:
1997 IUCN Red List of Threatened Plants
category V.

reducing to spines.
