Plants 150-500 mm high. Corm 25-60 mm diam.; tunics of densely matted fibres, with long collar. Stem flexed outward at ground level and then stiffly erect or inclined, unbranched, (1.5)2.0-3.0 mm diam. Basal leaves 4 or 5, dry and fragmented at flowering, in a basal fan, blades linear-lanceolate, 100-220 x 4-8 mm, acuminate, with 3 or 4 veins, not narrowed to a pseudopetiole below, firm-textured; cauline leaves 2 or 3, lowermost subulate and concealed in collar, uppermost vestigial and scale-like. Spike moderately densely ± 12-to 40-flowered, 150-400 mm long; bracts dry and brown, cartilaginous with membranous margins, oblong or ovate-oblong, 7-13 mm long, conspicuously apiculate, inner slightly longer. Flowers zygomorphic, dull dingy pink with dark reddish veins, unscented; perianth tube narrowly funnel-shaped, 6-11 mm long; tepals unequal, dorsal slightly larger, arched over stamens, oblanceolate-spathulate, clawed in lower 2/3, 20-25 x 3-4 mm, obtuse, other tepals suberect and recurved distally, 15-18 x 2.5-4.0 mm, upper laterals connate to lower laterals for ± 1 mm and lower 3 tepals joined at base for 3-5 mm. Filaments arcuate, later suberect, 13-16 mm long; anthers 6-7 mm long, yellow with small apiculus up to 1 mm long. Style 18-23 mm long, dividing opposite middle of anthers, branches ± 2 mm long.
