Historical notes:
Described in 1926 by English botanists
Otto
Stapf and
Joseph Burtt Davy.
Distinguishing features:
The robust stems and relatively narrow entire leaflets emerging with a
bluish tint and turning dark green with age place this species nearest to
E. lanatus and E. friderici-guilielmi. It is distinguished
from E. laevifolius by the keeled leaves that are distinctly
recurved at the tips and the densely woolly crowns, leaf-bases and cones.
E. friderici-guilielmi has straight leaves and more numerous cones.
Distribution and habitat:
Eastern Transvaal Province, South Africa, in grassland or low shrubs on
steep rocky slopes.
Conservation:
1997 IUCN Red List of Threatened Plants
category R.
