Described in 1990 by South African botanists
The subterranean habit with few stiffly erect leaves in the crown place this
species with E. ngoyanus, E. caffer and E.
umbeluziensis. It is distinguished within this group by the short leaves
with a distinct bluish bloom and well spaced leaflets bearing 1-2 teeth on
the lower margins towards the leaflet apex, the lower leaflets reducing to
spines, and the lack of wool in the crown. The orange seed cones are also
distinctive, in contrast to green cones in the other species.
