Plants 4-18(-30) cm tall. Corm almost conical, 6-10 x 10-18 mm, covered with numerous, finely to heavily reticulate, brown fibrous tunics, old corms persisting as flattened discs; fibres detaching from broad base, drawn upwards into a neck of thick, rigid, blunt bristles 5-55 mm long; roots arising from near corm base. Cataphylls present at onset of flowering, up to (15-)30-65 mm long, membranous, tipped with reddish-brown. Leaves 1-5, not sheathing above cataphylls, suberect, linear, up to 160(-250) x 1.5-2.0 mm, somewhat triangular to shallowly carinate, with obtuse midrib, dark green, firm-textured, margin entire. Inflorescences 1(2) in flower at a time, 1-flowered, exceeding leaves; scape up to 80 x ca. 1 mm, terete, pale reddish green; bract 1, incompletely sheathing pedicel almost up to apex, lanceolate, involute, 20-50 mm long, keeled distally, green, leathery, margin somewhat translucent distally, apex acuminate, entire. Flower pedicellate, stellate, yellow, backed with green in outer whorl, often reddish brown on midrib and margin, lightly scented; pedicel suberect, laterally deflexed in fruit, terete, 20-125 x ca. 1.0 mm, pale green; tepals 6, lanceolate, 6-17(-23) mm long, outer 3.0-5.0 mm wide, minutely mucronate, inner 2.0-3.5 mm wide. Stamens 6, slightly spreading, subequal or outer slightly shorter than inner, yellow; filaments inserted on ovary rim, slender, outer 1.0-2.5 mm long, inner 1.5-3.0 mm long, both whorls shorter than anthers; anthers linear, latrorse, 5-7 x 0.5 mm, basal lobes up to 0.5 mm long; pollen yellow. Ovary narrowly obconical, 4-7 x 1.7-2.0 mm, 3-locular; style 1.5-3.0 mm long; stigma branches erect, oblong, 3-6 x 0.7 mm, shorter than stamens, yellow, densely papillose. Capsule narrowly obconical, 6-7 x 2.5-3.0 mm, dehiscence circumscissile. Seeds depressed ovoid, ca. 0.62 x 0.52 mm; testa shiny black, of ca. 27 closely arranged longitudinal rows of cells, outer periclinal walls colliculate with a narrow, flat rim.
