Tuber 1-2 cm in diameter, spherical. Stems to 30 cm or more. Leaves 6-9 per plant; petiole flattened; lamina 5-17 x 2-6 cm, oblong, floating; base cordate; apex obtuse, apiculate. Spikes 3-12 cm, forked; peduncle usually swollen above. Flowers arranged all round the rhachis, the spikes characteristically tapering above; perianth segments 2, yellow. Stamens usually 6.

Spike bifid, lengthening during anthesis, 3-12 cm long, scape flattened, usually swollen above. Flowers white (in eastern Cape) or yellow, eventually somewhat laxly arranged all around the rhachis, the thick fruiting carpels below and the elongated young apical part giving the spikes their typically tapered appearance; perianth-segments 2, narrow-oblong to narrow-obovate, 2 mm long. Stamens usually 6, filiform, somewhat flattened, 2 mm long, spreading, anthers small, early deciduous, pollen ellipsoid, copious.
