Habit | Perennials; caudex simple; densely pubescent, trichomes 5–7-rayed, rays bifurcate or trifurcate. | Perennials; caudex branched; densely pubescent, trichomes (usually sessile, rarely short-stalked), several-rayed, rays furcate or bifurcate, (umbonate, 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. |
several from base, usually prostrate, rarely decumbent, (unbranched, often purplish, sparsely pubescent), to 1.5 dm. |
Basal leaves | blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers). |
blade deltate, hastate, or, less often, rhombic to elliptic, 1–5 cm, margins entire (often partially involute). |
Cauline leaves | (remote, proximal shortly petiolate); blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire. |
(proximal shortly petiolate); blade linear to oblanceolate, 0.5–1.5 cm, margins entire. |
Racemes | elongated. |
loose, elongated. |
Flowers | sepals linear-oblong, 5–7 mm, (lateral pair subsaccate); petals (erect), lingulate, 8–10 mm, (claw barely differentiated from blade). |
sepals (often purplish), oblong, lanceolate, or ovate, 4–6 mm, (median pair thickened apically); petals spatulate or cuneate, 5–8(–9) mm, (margins undulate). |
Fruiting pedicels | (recurved), 7–10 mm. |
(ascending, slightly sigmoid to straight), 5–10 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. |
ovoid or ellipsoid, slightly compressed, 3–5(–6) mm, (base often gibbous); valves pubescent, trichomes loose, furcate near their bases and spreading, sometimes sparsely pubescent inside; ovules 4(–8) per ovary; style 1.5–4 mm. |
Seeds | plump, (mucilaginous when wetted). |
flattened. |
