Characteristics

Dwarf, stemless, glaucous, tufted, densely villous, 2-4 cm high. Bulb elongate, up to 7 cm long, 2.5 cm broad; tunics, the outer lanceolate or linear-lanceolate, sharply acute, brown, with 3 conspicuous dark nerves, soon splitting from the base, the inner linear, pale brown. Rhizome slender, often 8-10 cm long, rarely bifurcate, with a few small membranous scales. Leaves numerous, densely congested; petioles 1-2 cm long, scale-like, membranous and 3-nerved below the basal articulation, densely villose with patent hairs; leaflets 3, subsessile, 4-6 mm long, cuneate-attenuate at the base, bilobed to about the middle, the lobes linear-oblong, divergent glabrous above, villose beneath, glaucous, minutely impresso-punctate when dried, the juvenile leaflets obcordate. Peduncles 1-fld., up to 2 cm long, villose, the articulation often 7 mm from the base; bracts 2, filiform, towards the apex. Sepals broadly lanceolate, 3-3.5 mm long, villoso-pubescent, ciliate, sometimes purple-dotted or lined. Corolla 0.9-1.6 cm long, white, with a short broadly funnel-shaped pubescent yellow tube; petals cuneate, subtruncate, pubescent and purple-dotted along the outer margin beneath. Filaments, the shorter 2-3.5 mm, the longer 3.5-6 mm long, minutely glandular-pilose, slightly gibbose, the longest exserted from the corolla tube. Ovary more or less pilose on the upper half, ecallose, the chambers about 12-ovuIed; styles glandular or pubescent. Seeds endospermous.
