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 simple or branched, (thickened, sometimes subterranean); densely pubescent, trichomes (sessile or short-stalked), 5–7-rayed, raysdistinct, bifurcate, (moderately to prominently tuberculate). | ||||||||
Stems | few to several from base, erect or outer decumbent, 0.5–2.5 dm. |
few to several from base, prostrate to decumbent or erect, (usually unbranched), 0.3–1.5(–3) dm. |
||||||||
Basal leaves | blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate. |
(petiole slender); blade suborbicular to obovate or elliptic, 1–8 cm, (base narrowing gradually or abruptly to petiole), margins sinuate-dentate or entire. |
||||||||
Cauline leaves | (proximal shortly petiolate, distal usually sessile); blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire. |
(proximal shortly petiolate, distal sessile); blade oblanceolate, 0.5–1.5(–2.5) cm, margins entire or remotely dentate. |
||||||||
Racemes | compact, (± subumbellate to densely corymbiform, elongated or not). |
dense or loose. |
||||||||
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 elliptic or oblong-elliptic, 4.5–7 mm, (median pair cucullate); petals spatulate, 7–9(–14) mm, (claw undifferentiated from blade). |
||||||||
Fruiting pedicels | (usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout). |
(sigmoid or curved), 5–10(–15) 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. |
(erect), ellipsoid to obovoid, compressed at apex and sometimes margins (strongly latiseptate), (5–)6–9 mm, (apex acute, often beaked); valves densely pubescent, trichomes appressed or spreading, sometimes sparsely pubescent inside, trichomes 4- or 5-rayed; ovules 4–12 per ovary; style (2–)3–6.5 mm, (often sparsely pubescent). |
