Plants 40-200 mm high. Corm globose, obliquely flattened toward base with crescent-shaped basal ridge ± as wide as corm, 6-10 mm diam., tunics splitting into fine parallel fibrils along ridge. Stem subterranean or aerial, exserted up to 150 mm. Leaves 3 to 5, lowermost 2 basal when stem exserted, filiform and narrowly 4-grooved, 0.5-1.0 mm diam. Peduncles up to 3, up to 60 mm long, semiterete, suberect in fruit; outer bracts green with narrow membranous margins, 12-30 mm long, sometimes keeled above, closely ribbed (3 or 4 veins/mm), inner bracts with broad, brown-flecked or-edged membranous margins. Flowers glossy rose-coloured to coppery salmon-pink, brick-red or pale pink to white, with small dark blotches or lines in throat, sometimes pale yellow at base of tube, outer tepals irregularly blotched pink and yellow on reverse; perianth tube narrowly funnel-shaped, 4-12 mm long; tepals elliptic or oblanceolate, 16-40 x 5-10 mm. Filaments inserted in middle of tube or slightly above, 4-10 mm long, pilose basally, yellow or maroon; anthers 5-10 mm long, golden-yellow. Style dividing shortly below to shortly beyond anther apices, branches 2-3 mm long, divided halfway. Capsules ellipsoid, up to 12 mm long.
