Erect, caulescent, fairly robust, 15-30 cm high, silky-pubescent, sometimes with glandular hairs admixed. Bulb conical or ovoid-conical, 4-6 cm long, with dark brown glabrous tunics; root contractile. Rhizome robust, with rather large amplexicaul cuspidate scales. Stem often 2 mm in diam., sometimes shortly branched, subsilky or hirsute, densely leafy or almost naked. Leaves numerous, both cauline, or tufted on short branchlets, and terminal, or nearly all terminally clustered; lower cauline petioles short, the upper and terminal 2-5 cm long; leaflets 3, subsessile, bifurcate to the middle or beyond, narrowly cuneate-attenuate at the base, with divergent oblong obtuse lobes 2-3 mm broad, glabrous above, silky-pubescent beneath, ciliate or more rarely glandular-ciliate, obscurely dotted all over with faint reddish-brown streaks which darken in drying. Peduncles 1-fld., axillary on the upper part of the stem, often 3-4 cm long, with 2 opposite bracts at an articulation above the middle. Sepals lanceolate, 4-6 mm long, often silky-pubescent, with several elongate calli towards the apex. Corolla 1.8-2.5 cm long, pubescent, rosy purple or white, with a broadly funnel-shaped yellow tube; petals obliquely subcuneate, slightly attenuate towards the base, obliquely subtruncate at the apex, 1.5 cm broad. Filaments, the longest 5.5 mm long, pubescent on the upper part, edentate or with short teeth. Ovary oblong, 2 mm long, glandular-pilose on the upper half, with elongate apical calli, the chambers 4-ovuled. Seeds endospermous.
