Rhizome slender, pale, often 5-7 cm long. Stem wiry, occasionally branched, 1-6 cm long, with 1 or more amplexicaul scales. Leaves few or many, terminally congested; petioles filiform, 0.5-2 cm long; leaflets 3, sessile, narrow-linear, conduplicate, often falcate, minutely emarginate, 0.3-1 cm long, glabrous above, sparsely pubescent beneath, not ciliate, usually with 2 or more reddish calli near the apex and sometimes obscurely and minutely callus-dotted on the upper part. Peduncles 1-fld., terminal, often 1.5-2.5 cm long, with 2 small subulate ciliate bracts a little below the calyx. Sepals more or less broadly lanceolate, up to 3 mm long, ciliate, often purplish at the apex and margins, inconspicuously bicallose at the apex. Corolla 1.2-1.7 cm long, glabrous, rose, filaceous or white, with a bright yellow funnel-shaped tube, rarely with a purple eye in the throat; laminae of the petals obliquely obovate, a little longer than the tapering claw, rarely purple-maculate on the outer margin beneath. Filaments, the shorter 3-4 mm, the longer 4-6.5 mm long, minutely glandular-pilose, unequal.
