- "TYPE: Mozambique, Chimanimani Mt, Munch 443; 444; 554 (holo PRE, SRGH) (= Munch ex Christian 770; SRGH, PRE); (= Dyer & Verdoon 5868; 5869; PRE)."
From the Chimanimani Mountains, eastern Zimbabwe, with the Latin termination
-ensis, place of origin.
Described in 1969 by South African botanists
Allen Dyer and
Inez Verdoon, who separated the
previously broadly defined E. manikensis into a number of segregates,
primarily on differences in pollen cone morphology (see also E.
concinnus, E. pterogonus and E. munchii).
A member of the E. manikensis complex, a group of robust cycads from
the region of the Zimbabwe-Mozambique border with stout erect trunks of
medium height, leaves with short petioles and numerous reduced spine-like
leaflets, median leaflets with 1-6 spines on each margin, green cones and
Distribution and habitat:
Known only from the Chimanimani Mountains on the broder between Zimbabwe and
