Erect, caulescent, rather weak, 5-20 cm high, clothed with viscous pluricellular capitate hairs. Bulb ovoid, acute at the apex, 1-1.5 cm long, with thin reddish-brown tunics, Rhizome slender, 2-6 cm long. Stem 2-14 cm long with a few scales at the base, often branching, with several subsessile or shortly petiolate leaves. Leaves mostly terminally congested or rarely verticillate on the upper part of the stem; petioles slender, often 1-2 cm long; leaflets 3, sessile, cuneate or linear-cuneate, dilated at the apex, conduplicate, emarginate, 0.5-1.2 cm long, glabrous above, the midrib beneath and margins ciliate with pluricellular capitate hairs, ecallose. Peduncles rather numerous, 1-fld., terminal on the stem and branches, rarely cauline, usually 2-4 cm long, with 2 minute bracts on the upper half, or ebracteate. Sepals lanceolate, 3-4 mm long, purplish on the upper part, ecallose. Corolla 1.2-1.6 cm long, glandular, yellow, with a broadly funnel-shaped tube; laminae of the petals obliquely triangular-obovate, about 4 times as long as the attenuate claw, often purple-margined beneath. Filaments, the shorter 3-4.5 mm, the longer 4-7 mm long, minutely glandular-pilose, distinctly gibbose. Ovary glandular-pilose on the upper half, ecallose, the chambers 2-3-ovuled.
