Historical notes: Described as a species of Zamia in 1775 by Swedish botanist Thunberg.

Distinguishing features: The dwarf, subterranean habit with few stiffly erect leaves in the crown place this species with E. ngoyanus, E. cerinus and E. umbeluziensis. I is distingiushed within this group by the short, dark green leaves with a spine-free petiole and entire, crowded, irregularly overlapping leaflets, and the woolly crown. Emerging leaflets are dull and densely tomentose, whereas those of E. ngoyanus are glossy and spersely hairy.

Distribution and habitat: Eastern Cape Province, South Africa, and Transkei, in grassland.

Conservation: 1997 IUCN Red List of Threatened Plants category V.
