Plants 120-250 mm long. Corm sub-globose, with bent, acuminate, grooved basal teeth. Leaves few, basal, filiform, 120-250 x c. 1 mm, grooves narrow. Bracts largely membranous or greenish in the centre of the upper half, often with purplish veins, with membranous margins and tips. Flowers 15-32 mm long, pale yellow, outer segments brownish on the backs. Perianth tube 5-9 mm long, narrow in the lower half, funnel-shaped towards the top; segments 8-20 x 4-5 mm. Filaments 4-5 mm; anthers 3-4 mm long. Style 8-10 mm; stigmas generally below the anther tips. Capsules often pushed underground by the strongly recurved peduncles which later coil up when dry.
