Historical notes:
Described in 1926 by English botanists
Otto
Stapf and
Joseph Burtt Davy.
Distinguishing features:
A robust, tall-growing species with glossy dark green leaves. Mature leaves
are straight and flat, with leaflets tending to droop away from the rachis.
Leaflets do not overlap, and are entire or carry 1-2 spines on the margins,
and 2-4 basal leaflets reduce to prickles, although leaving some clear
petiole. It is thought to be closest to E. transvenosus, which has
broader, overlapping leaflets with 3-6 prickles, and E. heenanii,
which has shorter trunks, shorter leaves that are held stiffly erect and
often twist at the tips, and entire leaflets.
Distribution and habitat: Swaziland and South Africa, Transvaal
Province, in mountain forests with fairly high rainfall.
Conservation:
1997 IUCN Red List of Threatened Plants
category V.
