Plants mostly 100-200 mm high. Corm globose, ± 15 mm diam., tunics of fine, pale fibres extending upward as collar around stem base. Stem unbranched or with a branch produced from base, with small cormlets in underground leaf axils. Leaves 6 to 10, all ± basal, reaching to ± base of spike, narrowly sword-shaped to sublinear, 2-9 mm wide, obtuse, obliquely apiculate, closely veined with ± prominent central vein. Spike slightly inclined, 1-to 3(4)-flowered, weakly flexuose, flowers spirally arranged; bracts dry, crinkled, translucent with light brown streaks, 15-18 mm long, lateral margins fimbriate, distally drawn into long tapering cusps, outer 3-veined and 3 prominently 3-cusped, inner 2-veined and 2-cusped, cusps often twisted or coiled. Flowers radially symmetric, pale to deep yellow to pale beige, often flushed brown or grey-purple on reverse of outer tepals, occasionally with small black spot near tepal bases, sweetly or unpleasantly sour smelling; perianth tube funnel-shaped, 6-8 mm long, narrow basal part ± 4 mm long; tepals subequal, ± oblong, 18-25 x ± 7 mm. Stamens symmetrically arranged; filaments erect, ± 6 mm long, enclosing style; anthers contiguous below, diverging above, 6-9 mm long, pale yellow. Style dividing opposite upper 1/3 of anthers, branches filiform below, gradually expanded and recurved in distal half, ± 5 mm long, extending outward between anthers. Capsules ± globose, 9-10 x ± 7 mm. Seeds light brown, up to 6 per locule, ± 2 mm diam.
