Leaf solitary; petiole 10--25 cm; leaf blade ternate, 2--5 × 3--6 cm, glabrous or sparsely pilose; petiolules 5--15 mm; central leaflet subentire, elliptic to ovate, base cuneate, margin serrate, apex acute to acuminate; lateral leaflets similar to central one, ovate, but often deeply 2-lobed so leaf blade appears 5-parted. Scape 15--25(--30) cm, glabrous; cyme 1--3-flowered. Involucral bract petiole 10--20 × 1--2 mm; bract blade ternate, similar to that of leaves but larger, 4--8 × 4--7 cm, sparsely puberulent; segments subsessile, central one undivided, lateral ones unequally 2-cleft. Bracteoles often 1 or 2, 3-parted, 1.5--2.5 cm. Pedicel 1.5--4 cm, densely puberulent. Sepals 5 or 6(or 7), bent or reflexed, white, linear-lanceolate, 5--7 × 1--3 mm, abaxially puberulent, basal veins 3, vein anastomoses absent. Stamens 2--5 mm; filament usually ovate-lanceolate or macelike, flat, dilated apically; anther ellipsoid or broadly ovoid. Ovary narrowly ovoid, ca. 2 mm, densely or sparsely puberulent, base narrowed; style straight, conic; stigma dilated.
