Small, erect, caulescent or rarely stemless, 5-12 cm high. Bulb oval or ovoid, slightly attenuate at the base and apex, 1-5-2.5 cm long: tunics hard, brown. Rhizome up to 5 cm long. Stem 2-5 cm long, glabrous, with a few small scales. Leaves 3-8, apically congested: petioles 2-4 cm long, glabrous or sparsely pubescent: leaflets 3, very shortly petiolulate, rhomboid-oval or rhomboid-ovate, obtuse, the lateral oblique, 1-2 cm long, 0-6-1-1 cm broad, glabrous or sparsely villose, digitately veined, sometimes nigro-punctate, dark green above, purple beneath, brownish-green on both faces when dried. Peduncles 1-fld., usually about as long as the leaves, pubescent particularly on the upper half, with 2 minute opposite bracts, orange-callose at the apex, set at an upper articulation a little above the middle. Sepals lanceolate, obtuse or subacute, more or less pubescent, rarely glabrous, 3.5-5 mm long, sometimes with 2 minute apical calli. Corolla 1.3-1.9 cm long, yellow, with a broadly funnel-shaped concolorous tube: laminae of the petals broadly cuneate-obovate, up to 1 cm broad, often purple-striate on the outer margin, attenuate to a short claw. Filaments, the shorter 2.5-4 mm, the longer 4.5-7.5 mm long, glabrous or minutely glandular-pilose, shortly and broadly toothed, the longest (or the styles) somewhat exserted from the corolla tube. Ovary oblong, 1.7-2.5 mm long, pubescent on the upper half, dotted with small purple calli, the chambers 5-ovuled: styles pubescent below, glandular-pubescent above.
