Herbs, perennial, caespitose, (5-)10-15(-20) cm tall. Rootstock often much branched at apex, with some scales and residual petiolar bases. Stems from scales or radical leaf axil, usually with 2 opposite or nearly opposite small leaves on lower part, or with 1-3 scattered leaves. Radical leaves many, ca. as long as stems or slightly longer; petiole broadly vaginate at base, 3-7 cm; blade glaucous abaxially, green adaxially, oblong, 4-8 × 2-3.5 cm, pinnate; pinnae 3 or 4 pairs, petiolulate or sessile, deeply divided into oblanceolate or obovate distinctly mucronate lobes 3-10 × 2-5 mm, sometimes lobes again divided. Cauline leaves small, shortly petiolulate, vaginate. Racemes corymbose, 5-10-flowered; bracts 15-20 mm, cuneate, palmately lobate, or upper ones entire; lower pedicels 20-35 mm. Sepals ca. 1 × 1 mm, dentate. Corolla yellow; outer petals without crest, or rarely with narrow crest; upper petal 2-2.2 cm, subacute; spur nearly straight, cylindric, 9-10 mm; nectary thin, extended through ca. 1/2 of spur; lower petal ca. 1 cm, base broadly and shallowly saccate, apical 1/2 reflexed, rather broad, subobtuse; inner petals 8-9 mm, claw ca. 1/2 as long as limb. Ovules 8-10 in 2 rows; stigma square, apex slightly emarginate, apical papillae often confluent, laterally and on basal lobes with geminate papillae.
