Ecology and distribution
Trop. Afr.
Biology : Herb 20-50 cm tall, flowering with the leaves; tuber ± globose, simple, to 4x4,5 cm; skin rough, dark brown, flesh pink to red, growing point apical; old leaf-sheaths to 6,5 cm long, forming a fibrous neck; leaves 2-5, ± erect; leaf-sheaths barely exserted; blade narrowly to broadly ovate, 4-15x1,5-6,2 cm, basally channelled and clasping the inner sheaths; scape to 40 cm long, 4 mm Ø; raceme to 24x3,5 cm, cylindrical to narrowly conical, to 50-flowered; flowers to 2,1 cm Ø, campanulate; tepals ligulate, 5-10 mm long, bright yellow with a green midnerve; capsule obovoid, to 8x7 mm.
Ecology : Grassland in damp places; copper-poisoned dembos; mixed savanna or grassland; rocky grassland; quartzite grassland above the level of Brachystegia tamarinoides vegetation; 50-2000 m alt.
  Sometimes difficult to distinguish from E. triphyllum: robust plants in E. Africa rather belong to E. triphyllum, but difference in leaf-shape seems to be more important than robustness to distinguish the two species.
