Herbs perennial, acaulous, rhizomes and stolons absent, bulbs solitary or clustered; mostly 8–15 mm diam.; outer bulb scales 3[–5]-nerved, inner scales thick, reddish brown, rugose. Leaves basal; petiole 1.5–15 cm, sparsely villous or glabrous; leaflets 3, green, rounded-obcordate, 4–18 mm, lobed 1/6–1/5 length, lobes apically convex to nearly truncate, margins prominently ciliate, hairs stiff, sharp-pointed, abaxial surface strigose to hirsute-strigose, densely hirsute at very base, adaxial surface glabrous, oxalate deposits absent. Inflorescences umbelliform cymes, 1(–2)[–4]-flowered; scapes 3–27 cm, glabrous or sparsely hirsute-villous proximally. Flowers apparently tristylous (mid-styled flowers observed); sepals yellowish green, apices with 2 orange, elongate tubercles; petals yellow basally, otherwise deep rose to purple or violet, with dark purple veins proximally, 11–20 mm. Capsules fusiform, mature size not observed, indumentum not seen.
