The species is common throughout its range and is the most frequently cultivated in Southern Africa, largely because of its affordable price. As a result of its large geographical distribution, it is notably variable in leaf and cone shape. A largely underground trunk results in very little of the plant being visible, so that it is described as a dwarf species. The preferred habitat of this species is frost-free coastal bush. It hybridises readily with Encephalartos altensteinii in the Eastern Cape and with Encephalartos lebomboensis in the Pongola area. The crown normally consists of tightly-packed bracts covered in dense grey woolly hair (villosus = hairy). As with all cycads this species is dioecious. Male plants may carry up to 15 cones, whereas only one or two occur on the females. The seeds, embedded in bright-red flesh are eaten and distributed by the purple-crested lourie (Tauraco porphyreolophus) and by the trumpeter hornbill (Bycanistes bucinator).[2] GalleryReferences1. ^{{IUCN| id = 41947/| taxon = Encephalartos villosus | assessor =Donaldson, J.S.| assessment_year = 2009| version = 2015.3| accessdate = 15 November 2015}} 2. ^Douglas Goode - Cycads of Africa - Struik Wincester 1989 External links{{commonscat-inline}}{{Taxonbar|from=Q144446}} 6 : Encephalartos|Flora of the Cape Provinces|Flora of KwaZulu-Natal|Flora of Swaziland|Garden plants|Plants described in 1868 |
