Habit | Perennials; caudex simple; densely pubescent, trichomes 5–7-rayed, rays bifurcate or trifurcate. | Perennials; caudex simple or branched, (sometimes enlarged); densely pubescent, trichomes (sessile), several-rayed, rays fused (webbed) most of their length, (umbonate, peltate, tuberculate throughout). |
Stems | several from base, erect or outer usually decumbent toward base, (from below a terminal tuft of mostly erect leaves, unbranched), 1–2 dm. |
few to several from base, erect or outer ones decumbent, 0.5–4 dm. |
Basal leaves | blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers). |
(long-petiolate); blade elliptic to obovate or rhombic, 2–6(–9) cm, margins entire. |
Cauline leaves | (remote, proximal shortly petiolate); blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire. |
(sessile or shortly petiolate); blade oblanceolate to spatulate, 1–3 cm, (proximal broader), margins entire. |
Racemes | elongated. |
dense, (relatively short). |
Flowers | sepals linear-oblong, 5–7 mm, (lateral pair subsaccate); petals (erect), lingulate, 8–10 mm, (claw barely differentiated from blade). |
sepals elliptic or narrowly oblong, 4–5.4 mm, (tapered to apex); petals (white, base and claw yellow, conspicuously purple-veined), usually broadly obovate or rhombic, 6–10 mm, (± equal to blade, tapering to slender claw). |
Fruiting pedicels | (recurved), 7–10 mm. |
(erect to spreading, ascending, or (proximal) horizontal, straight to slightly curved, sometimes loosely sigmoid), 6–12(–20) mm. |
Fruits | (usually pendent, sessile), subglobose, slightly flattened (angustiseptate), 4–5 mm; valves densely pubescent, trichomes somewhat spreading; ovules 8–12 per ovary; style 4–5 mm. |
(sessile or substipitate, often reddish magenta), usually ovoid to subglobose, inflated, 4–6(–7) mm; valves (not retaining seeds after dehiscence), glabrous; replum as wide as or wider than fruit; septum perforate; ovules 8–12 per ovary; style 1.5–4 mm. |
Seeds | plump, (mucilaginous when wetted). |
somewhat flattened. |
