Characteristics

Herbs, perennial, densely caespitose, 4-10 cm tall, slightly to very glaucous. Rootstock elongate, simple or often branched, apically with remnants of dead petioles and scales (in FRPS reported to have scales with axillary bulbils). Stems few to several from radical leaf axils, simple, naked or with 1 or 2 leaves in lower 1/3. Radical leaves many, longer than stems; petiole 3-6 cm, broadly vaginate at base; blade crisped, oblong, 3-6 × 1-2 cm, bipinnate; pinnae 4-6 pairs, lower ones distant, sessile; pinnules 2 or 3 pairs, dense, sessile, twice 3-5-parted; ultimate lobes ovate, ca. 2 × 1 mm, fleshy. Cauline leaves like radical leaves but smaller or much reduced. Racemes ± corymbose, 4-8-flowered; lower bracts oblong, acute, coarsely dentate to lobed, ca. 10 × 8 mm; upper bract lanceolate and entire; lowermost bract sometimes without flower. Pedicel 10-15(-20) mm, stout, soon arcuate, becoming more recurved in fruit. Sepals long persistent, whitish, ovate to reniform, ca. 2 × 2 mm, deeply dentate. Corolla yellow; outer petals with broad obtuse entire crests, slightly overtopping apex, limb rather broad or with rounded lobes; upper petal 16-17 mm, crest nearly extended to spur central part; spur cylindric, short and broad (rarely narrow), 6-8 mm; nectary extended through 1/2-2/3 of spur; inner petals 8-9 mm, claw shorter than limb. Stigma broader than long, apically emarginate, each 1/2 with 4 papillae; geminate papillae lacking. Mature capsule unknown, presumably narrowly oblong; style 2-2.5 mm.
