Habit | Perennials; caudex simple or branched, (thickened by persistent leaf bases); densely pubescent (foliage usually scabrous), trichomes (sessile or short-stalked), several-rayed, rays furcate near base, (usually strongly umbonate, roughly tuberculate, less so over umbo). | Perennials; caudex branched, (thickened, cespitose); densely pubescent, trichomes 5- or 6-rayed, rays slightly fused at base, furcate or bifurcate, (tuberculate throughout). | ||||
Stems | few to several from base, erect or outer decumbent, 0.5–2.5 dm. |
few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm. |
||||
Basal leaves | blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate. |
blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded). |
||||
Cauline leaves | (proximal shortly petiolate, distal usually sessile); blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire. |
blade spatulate, margins entire. |
||||
Racemes | compact, (± subumbellate to densely corymbiform, elongated or not). |
compact, subumbellate. |
||||
Flowers | sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically); petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated). |
sepals (pale yellow), 4–5 mm; petals lingulate, 6–7 mm. |
||||
Fruiting pedicels | (usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout). |
(ascending, curved to slightly sigmoid), 5–8 mm. |
||||
Fruits | (sessile or shortly stipitate, less than 1 mm), subglobose to broadly ellipsoid, inflated or slightly compressed (terete or subterete), (4–)5–8(–9) mm; valves (not retaining seeds after dehiscence), glabrous; replum as wide as or wider than fruit; ovules 8–16 per ovary; style 4–8(–9) mm. |
ovoid to ellipsoid, slightly inflated, (apex not compressed), 3–4 mm; valves pubescent, trichomes erect on mature fruits, (± appearing fuzzy); ovules 8 per ovary; style 4–5 mm, (glabrous). |
||||
Seeds | flattened. |
