Ecology and distribution
Trop. Afr.
Biology : Slender vine 5-6 m long, climbing up trees or spreading over lower shrubs, sometimes trailing along ground, glabrous to ± pubescent; tuber c. 10 cm long, ovoid, lobed or a main tuber with several smaller tubers in dense clusters 2,5-7 cm Ø, with dense fibrous roots; indumentum of simple straight hairs 0,1-0,6 mm long; stems unarmed, left-twining, c. 5 mm Ø, sometimes with small bulbils in leaf axils; leaves alternate, digitately 3-7-foliolate, rarely entire; petiole 0,5-10 cm long; petiolules 0,5-5 mm long; leaflets elliptic to oblanceolate to obovate or linear or rhombic, 1-15x0,4-6 cm, each leaflet with 1 midrib, excurrent forming an apiculus 2-9 mm long, densely woolly-pubescent above and beneath to pubescent only on veins and margins; male inflorescences with peduncle 0,4-3,8 cm long, 1 or 2-7 looking like catkins, 3-6 cm long, in axils of upper leaves, or often in pendulous leafless panicles to 40 cm long, flowers hidden by bracts; female inflorescences pendulous, spicate, to 17 cm long; flowers sweet-scented; capsule ± oblong, 1,5-3,4x1-1,8 cm, ± hairy; seed winged on basal side only, 3,5-7 mm long.
Ecology : Open spaces in rain-forest; riverine forest; forest edges; termite hills; scrub; thickets; often on hillsides and near rock outcrops; Acacia, Commiphora woodland; deciduous wooded grassland with Anogeissus, Boswellia, Acacia, Cussonia spp.; broken sandstone; 0-2650 m alt. – The most widespread Dioscorea in Africa.
  Polymorphic species, and a number of forms exist, and there are intermediates between all the forms, which make an infraspecific classification impossible.
