Leaves 3-16, terminally congested, rarely 1-2 cauline; petioles slender or filiform, very short or up to 1.2 cm long; leaflets 3, sessile, linear or narrowly linear-cuneate, 0.5-1 cm long, often conduplicate, emarginate, glabrous, bicallose at the apex and sometimes with a row of elongate calli near the margins, or ecallose. Peduncles 1-fld., terminal, 2-6 cm long, rarely densely clothed with gland-tipped hairs, with 2 small alternate lanceolate bracts close to the calyx.
