Leaves.10-20, apically congested: petioles 0.5-1.5 cm long, sparsely glandular-pilose: leaflets 3, sessile, linear or narrowly linear-cuneate, falcate, conduplicate or involute, emarginate, 4-9 mm long, glabrous, with a few pellucid streaks which turn black in drying. Peduncles 1-fld.,rather numerous, apical, 1.5-2 cm long, or if arising from the upper cauline scales, rather longer, with 2 minute alternate subulate callose bracts near the calyx.

Corolla 1-1. 6 cm long, white, with a funnel-shaped yellow tube: petals somewhat ascending, cuneate, rounded at the apex, longitudinally concave, up to 3.5 mm broad, with linear calli along the margin. Filaments, the shorter 2-3.5 mm, the longer 3-5 mm long, sparsely glandular-pilose on the outer edge, slightly gibbose.
