Stems (15-)30-50(-80) cm; base reddish, nearly glabrous. Leaves mostly cauline; basal leaves 0-3 at anthesis; cauline leaves 2-5 at anthesis; petiole 3-15 cm. Leaf blade round to pentagonal, 1.5-4 × 3-7 cm, nearly glabrous; ultimate lobes 3-7, distinctly wedge-shaped, usually 5 or fewer extending 3/5 distance to petiole, width 5-20 mm (basal), 1-15 mm (cauline), widest in distal 1/2. Inflorescences 5-20(-38)-flowered; pedicel spreading from rachis at nearly 90° 1-3(-4) cm, glabrous or glandular-pubescent; bracteoles (7-)11-19 mm from flowers, blue or green, linear, 2-5 mm, puberulent to glabrous. Flowers: sepals dark bluish purple to pink or white, usually retaining color upon drying, glabrous, lateral sepals reflexed, 6-10(-13) × 3-6 mm, spurs often curved upward, within 30° above or below horizontal, 8-12(-14) mm; lower petal blades elevated, exposing stamens, 3-5 mm, clefts 1-3 mm; hairs almost exclusively near base of cleft, centered or mostly on inner lobes, usually yellow. Fruits 8-16 mm, 3-3.5 times longer than wide, glabrous to glandular-puberulent. Seeds unwinged; seed coats ± pitted, cell surfaces roughened.
