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; (flowering in the first year); caudex branched, (well-developed); densely pubescent, trichomes (subsessile, appressed to spreading), 3–6-rayed, rays furcate or bifurcate, usually slightly fused at base, less frequently distinct. | ||||
Stems | few to several from base, erect or outer decumbent, 0.5–2.5 dm. |
few to several from base, ascending (in flower) to nearly prostrate (in fruit), (unbranched), 1–2.5 dm. |
||||
Basal leaves | blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate. |
(petiole 1–3.5 cm); blade ovate to rhombic or rotund, 2–7 cm, (base narrowed abruptly to petiole), margins usually entire, occasionally shallowly repand, (flat). |
||||
Cauline leaves | (proximal shortly petiolate, distal usually sessile); blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire. |
blade elliptic or narrowly so, (0.7–)1–2.5 cm, (base narrowed gradually to petiole), margins entire. |
||||
Racemes | compact, (± subumbellate to densely corymbiform, elongated or not). |
dense, (elongated in fruit). |
||||
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 (lavender under grayish trichomes), elliptic, 4–6 mm; petals (white, pale yellow basally, often tinged lavender abaxially), narrowly spatulate, 6–10 mm, (claw undifferentiated from blade). |
||||
Fruiting pedicels | (usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout). |
(ascending, curved to slightly sigmoid), (4–)6–12 mm, (stout). |
||||
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. |
subglobose to ovoid, slightly compressed, 5–7 mm; valves densely pubescent, trichomes spreading; ovules 8–12 per ovary; style 4–6 mm. |
||||
Seeds | flattened. |
flattened, (faintly margined). |
