Glabrous perennial herb, with a cylindrical tuberous root to 10 × 1.5 cm producing a woody subterranean stem to 6 cm. long and annual stems to 7 cm. high; leaves subsessile, linear-oblanceolate to 11 × 2 cm, apex rounded, margins minutely crisped, midrib ± keeled beneath, lamina often tinged red on the undersurface; cymes on peduncles to 2.5 cm. long, 1-forked with cyme-branches to 1.5 cm. long, or cyathia solitary, peduncles and cyme-branches with longitudinal winged ridges; bract-cup ± equal to the involucre, ± 6 × 10 mm., notched to ± halfway between acute apices and keeled midribs, green with darker veining; cyathia ± 5 × 4 mm., with cup-shaped involucres; glandular rim ± 2 mm. high, entire, pink, lobes rounded, ± 1.3 × 1.3 mm; male flowers:bracteoles few, filamentous; stamens 4 mm, long; female flower:perianth an obvious ± lobed rim ± 0.5 mm. wide; styles 2 mm. long, joined to halfway with thickened rugulose distinctly bifid apices; capsule exserted on a pedicel to 6 mm long, obtusely 3-lobed, ± 5 × 6 mm, with a fleshy ridge along each angle; seeds subglobose, 2.8 × 2.5 mm, black with shallow yellowish tubercles; caruncle sessile, 1 mm in diameter.
Var. pseudoracemosum from Tanzania along the south eastern shore of Lake Tanganyika differs in having obovate leaves up to 7.5 x 6 cm with margins entire.
