Stems (10-) 20-50 (-80) cm; base reddish or not, not longitudinally ridged, long-pubescent. Leaves mostly on proximal 1/3 of stem; basal leaves 0-6 at anthesis; cauline leaves 1-6 at anthesis; petiole 0.5-9 cm, petioles of proximal leaves long-pubescent. Leaf-blade round to pentagonal, 1-4.5 × 2-6 cm, pubescent; ultimate lobes 3-15, width 3-8 mm (basal), 2-5 mm (cauline). Inflorescences (4-) 6-17 (-20) -flowered, open; pedicel 0.5-3 (-7) cm, usually puberulent; bracteoles 2-7 (-23) mm from flowers, green, linear-lanceolate, 3-8 mm, puberulent. Flowers: sepals usually deep royal blue, sometimes bright blue to light blue or white, ± finely pubescent, lateral sepals spreading, 10-18 (-25) × 6-10 mm, spurs straight, ascending ca. 30° above horizontal, 10-19 mm; lower petal blades slightly elevated, ± exposing stamens, 4-11 mm, clefts 0.5-3.5 mm; hairs sparse, more on inner lobes than outer lobe or centered, scattered on margins, white or yellow. Fruits 9-19 mm, 2.2-3.8 times longer than wide, ± puberulent. Seeds not echinate, appearing ± smooth to naked eye; seed-coat cells with margins ± undulate, surfaces roughened.
