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; (delicate, short-lived); caudex simple, (sometimes elongated, covered with persistent leaf bases); usually sparsely pubescent, trichomes 7–12-rayed, rays furcate near base. | ||||
Stems | few to several from base, erect or outer decumbent, 0.5–2.5 dm. |
simple from base, erect to decumbent, (unbranched, mostly filiform, slender), 1–1.5 dm. |
||||
Basal leaves | blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate. |
(erect, petiole slender); blades broadly ovate to elliptic, 0.5–1 cm, (base abruptly narrowing to petiole), margins entire. |
||||
Cauline leaves | (proximal shortly petiolate, distal usually sessile); blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire. |
(remote, distally shortly petiolate); blade ± spatulate, (base cuneate), margins entire. |
||||
Racemes | compact, (± subumbellate to densely corymbiform, elongated or not). |
lax, (elongated, few-flowered). |
||||
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 (erect), oblong, 3.5–4 mm, (lateral pair not saccate); petals (often fading to light purple apically), spatulate to nearly lingulate, 6–7 mm. |

Fruiting pedicels | (usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout). |
(recurved to widely spreading, filiform, slender), 5–10 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. |
(pendent), globose or subglobose, compressed, 3–4 mm; valves ± densely pubescent; ovules 6–10 per ovary; style ca. 1.5 mm. |
