Basal leaves absent at flowering time, pinnate with 3 or 4 pairs of lateral lobes; lobules alternate to subopposite, ovate to oblong, 1.5-5 × 1.4-2.5 cm, end lobe larger than lateral ones, both surfaces and margin sparsely yellow-brown shortly barbellate-setose, later glabrous or only with remaining scabrous firm bases, base auriculate, margin pinnately lobate, apex obtuse to rounded. Upper cauline leaves lanceolate, 5-12 × 2-3 cm, merging with bracts, often auriculate at base. Inflorescence many flowered, paniculate below, racemose above, lower branches usually 3-flowered, upper ones 1-flowered; peduncles 4-8.5 cm, pubescent like stems. Pedicel 4-5.8 cm, slender, pubescent like stems, but apically more densely so. Petals 4, pale yellow, obovate or suborbicular, 1.8-3.1 × 1.6-2.8 cm. Filaments filiform; anthers orange to black-brown. Ovary spherical to elliptic, 1.5-1.8 cm × 8-10 mm, densely appressed or inclined setose; styles distinct, 7-8 mm; stigmas capitate.
