Gregarious, herbaceous, sub-scapose chamaephytes, 0.3-0.6 m tall, from a small hard rhizome, bearing long, hard roots (Note: plants from Natal possess thinner roots). Leaves mostly basal, 3-4, linear, up to c. 200 mm long and c. 10 mm broad, smooth, glabrous except for ciliate, open, sheathing basal part. Flowering shoot up to 0.5 m tall, the peduncle bearing a few reduced leaves; thyrse terminal or terminal and axillary, with few to many divaricate branches bearing close-set, secund scars of early flowers. Flowers slightly zygomorphic, opening in late afternoon for a few hours. Sepals 3, ovate, c. 5 mm long, green, persistent. Petals 3, equal, obovate, c. 10 mm long, mauve. Stamens: 2 upper antesepalous, fertile, and curved downwards, the 3rd sterile; filaments yellow with long, purple, beaded hairs; 3 antepetalous staminodes with glabrous filaments, the empty anthers tri-lobed. Ovary with 2 superposed ovules in each locule; style curved upwards, stigma terminal, small. Capsule oblong-globose, c. 6 mm long, shiny; seeds oblong-globose, truncate where they meet, c. 1.5 mm long, the transverse ribs tuberculate, reticulate.
