Erect, caulescent, slender, 8-18 cm high, pubescent either with simple or simple and capitate hairs admixed. Bulb ovoid or oblong-ovoid, attenuate at the apex, up to 6 cm long, with brown splitting tunics. Rhizome 8-10 cm long, clothed, at least below, with a tunicaceous cortex. Stem wiry, rarely branched, 5-15 cm long, rather densely pubescent below, sparsely pubescent or glabrous above, with 1-4 scales or more rarely subsessile leaves. Leaves terminally congested; petioles filiform 0.5-1.5 cm long; leaflets 5-8, sessile, linear or linear-oblong, obtuse, minutely emarginate, conduplicate or involute, 4-10 mm long, much enlarged after the flowering period, glabrous above, pilose beneath, ciliate, with several small brown calli on the upper part. Peduncles 1-fld., slender, terminal or very rarely arising from a stem-scale, rarely exceeding the leaves, with 2 alternate subulate bracts on the upper part. Sepals lanceolate, 4-5 mm long, sometimes purple-margined. Corolla 1.5-2 cm long, pubescent or glandular-pubescent, rose or violaceous, with a rather narrowly funnel-shaped yellow tube; laminae of the petals broadly and obliquely obovate, 6.5-10 mm broad, greenish-buff or purple on the outer margin beneath, about as long as the narrow claw. Filaments, the shorter 2.5-5 mm, the longer 5-7.5 mm long, sparsely glandular-pilose, gibbose or shortly toothed. Ovary pubescent on the upper part, the chambers 2-ovuled; styles pubescent below, with pluricellular hairs above. Capsule subglobose. Seeds without endosperm.
