Historical notes: Described in 1867 by Belgian botanist - Lem.

Distinguishing features: The very narrow leaflets with recurved margins are unique to this species. E. cycadifolius may have leaflets almost as narrow, but these are not recurved and lack the persistent grey wool often present in E. ghellinckii. E. friderici-guilielmi has similar leaflets to E. cycadifolius, but usually broader.

Distribution and habitat: Mountanous regions of Natal Province of South Africa and Transkei, in grasslands on rocky ridges and slopes.

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