Stemless, 5-8 cm high. Bulb more or less ovoid, acute, usually 2-3 cm long; tunics dark brown, gummy. Rhizome 5-15 cm long, with submembranaceous semiamplexicaul scales. Leaves few or many; petioles usually 2-4 cm long, densely or sparsely villoso-pubescent or glabrescent; leaflets 3, cuneate-rotund or cuneate-obovate, usually emarginate, sometimes attenuate at the base, the medial 0.6-1.1 cm long, 0.7-1.3 cm broad, the lateral oblique, a little smaller, glabrous or pubescent above and beneath, often very narrowly cartilaginous-margined, usually ciliate sometimes with both patent and introrse hairs, rather conspicuously veined, often purplish, and in some specimens minutely nigro-punctate beneath. Peduncles 1-fld., up to 8 cm long, villose, with 2 minute filiform bracts at an articulation slightly above the middle. Sepals broadly lanceolate or oblong-lanceolate, usually obtuse, 4-6 mm long, often with 2 small apical calli. Corolla 1.6-3.3 cm long, yellow, with a rather narrowly funnel-shaped tube; laminae of the petals very broadly cuneate-obovate, subtruncate, rather longer than the narrow claw. Filaments, the shorter 2-3.5 mm, the longer 3.5-6.5 mm long, glabrous or minutely glandular-pilose, with long acute teeth.
