Morphology General Habit
Perennial herb from a short rhizome, with spreading fleshy roots 3–5 mm in diameter, and several thin fibrous roots.
Morphology Leaves
Leaves linear to linear-lanceolate, flattened, terete or 3-angled and grooved, up to 36 cm long, 2–8(–12) mm wide, hollow and pithy inside, expanding at the base into a tubular sheath, the outer leaves reduced to membranous sheaths up to 4.5 cm long.
Morphology Reproductive morphology Inflorescences
Peduncle at anthesis 10–18(–25) cm long, 1–3 mm wide, shorter than the leaves; raceme at anthesis 1.5–3.5 cm long, 1.2–1.7 cm in diameter; bracts cuspidate, up to 12 mm long, 2–3 mm wide at the base, attenuate into a filiform apex which is slightly recurved, membranous and transparent exceptfor a brown midrib; pedicels 2–4 mm long, overtopped by the bracts at anthesis, recurved after flowering.
Morphology Reproductive morphology Flowers
Flowers congested, white; tepals 5–6 mm long, the outer ± 2 mm wide, 3-nerved, the inner ± 1 mm wide, 1-nerved; stamens 3–4 mm long, yellow; ovary ± 1 mm long; style ± 4 mm long.
Morphology Reproductive morphology Fruits
Capsule obovoid, ± 4.5 mm long, ± 4 mm wide, not inflated at maturity; seeds deltoid, angled, ± 2 mm wide.
Habitat
Woodland, thicket or seasonally wet grassland, sometimes on termite-mounds; 800–1050 m

Morphology Reproductive morphology Inflorescences Peduncles
Peduncles 1–3, erect, simple, similar to the leaves, 12–32 cm long, about two-thirds as long as the leaves.
Morphology Reproductive morphology Inflorescences
Racemes ± densely many-flowered, cylindrical, 1.5–4.5 cm long at anthesis, increasing to c. 7 cm long in fruit; bracts white membranous with a darker midrib, longer than the pedicels, 7–12 mm long, lanceolate with a subulate apex, exauriculate, persistent; pedicels erect to ascending becoming recurved in fruit, 5–9 mm long, persistent.
Morphology Reproductive morphology Flowers Tepal
Tepals white, 4–6 mm long, the outer c. 2 mm wide and 3-nerved, the inner c. 1 mm wide and 1-nerved, spreading for a short time before closing about the developing fruit.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments 2–3 mm long, densely bearded in the upper part; anthers c. 1.2 mm long.
Morphology Reproductive morphology Flowers Gynoecium Style
Style c. 4 mm long, terete.
Morphology Reproductive morphology Fruits
Capsule not inflated when mature, 3.5–4.5 mm long and 4–4.5 mm wide, broadly obovoid, markedly 3-lobed with broad deep grooves between the lobes.
Morphology Reproductive morphology Seeds
Seeds 2 per locule, c. 2–3 mm across, pyramidal, not winged, convex on the outer face with 2–3 flat inner faces tapering to the point of attachment, shiny black.
Morphology General Habit
Erect perennial herb, 20–50 cm tall.
Vegetative Multiplication Rhizomes
Rhizome much abbreviated, 2–4 mm long and 4–10 mm in diameter; roots few to numerous, radiating, fleshy, fusiform-tuberous, up to 4 cm long and 7 mm in diameter, with some slender fibrous roots interspersed.
Morphology Leaves
Leaves 4–10, subterete, pithy or hollow, ± finely tapering to the apex, ± flattened at the base, the outer 2–5 abruptly expanded in the basal c. 2–4 cm into thin hyaline sheathing wings up to c. 10 mm wide on each side of the lamina, the outermost wings completely enfolding the inner; blades up to 50 cm long and 2–6 mm in diameter, ± reduced or absent in the outermost leaves (squamae).
