Encephalartos lanatus

Encephalartos lanatus Stapf & Burtt Davy, "Fl. Transvaal & Sw. 1: 40, 90, fig. 4d" (1926). H—PRE
"TYPE: Republic of South Africa, Middelburg Distr., Toevlugt 472, Weeber H6471 (holo PRE)."

Etymology: Latin lanatus, woolly




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.
