latin concinnus, neat or trim, from the compact and attractive habit.
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.
munchii, E. pterogonus and E. chimanimaniensis).
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:
Scattered and sporadic, in small populations in southern Zimbabwe, in
woodland or grassland on cliffs and rocky hills.
