Plants 1-30 cm tall. Corm somewhat globose, 8-25 mm diam., outer covering more or less smooth, corky to leathery, sometimes fissured and appearing roughly fibrous, occasionally partially covered by roots; roots spreading from corm proximally and distally. Cataphylls membranous, up to 17 mm long. Leaves 2-7, sheathing up to 25 mm above base, recurved, lorate, 70-300(-500) x 3-10(-14) mm, carinate, tapering evenly upwards, softly thin-textured, margin entire. Inflorescences (1)2 or 3 in flower at a time, 2-5-flowered; scape up to 35-150 x 1.5-1.7 mm, more or less 3-angled in cross section, pale green, sharp corners hyaline; bracts 2-5, loosely clasping pedicels proximally or nearly entire length, lanceolate, 17-60 x 2.5-7.0 mm, keeled, thin-textured, pale green. Flowers pedicellate, stellate, sulphur yellow, backed with green in outer whorl, sometimes narrowly striped with red, unscented; pedicels spreading, more so in fruit, 20-87 x ca. 1 mm, compressed, pale green; tepals 6, often fused at base up to 1 mm long, sometimes somewhat reflexed, oblong-lanceolate, 5-16 mm long, outer 3.0-5.0 mm wide, minutely mucronate, inner 2.5-3.5 mm wide. Stamens 6, slightly spreading, subequal or outer slightly shorter than inner, yellow; filaments inserted near base of tepals, 1.5-2.5 mm long, shorter than anthers; anthers oblong, latrorse, 2.5-5.0 x ca. 1 mm, basal lobes ca. 0.5 mm long; pollen yellow. Ovary narrowly obconical, somewhat 3-angled in cross section, 3.5-10.0 x 2 mm, 1-locular, with 3 parietal placentae; style ca. 1.5 mm long; stigma branches erect, lanceolate, 4.5-6.5 x 0.7-1.7 mm, unequal, slightly shorter to longer than stamens, yellow, sometimes with basal lobes 1.5-2.0 mm long, yellow, densely papillose. Capsules obconical, 8-17 x 3-4 mm, dehiscence circumscissile. Seeds ellipsoid, ca. 0.5 x 0.4 mm; testa black or rusty brown, of transversally widened cells, forming ca. 12, broad, longitudinal ribs.
