Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | 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 | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
few to several from base, ascending (in flower) to nearly prostrate (in fruit), (unbranched), 1–2.5 dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
(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 often narrowed to short petiole, distal sessile); blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire. |
blade elliptic or narrowly so, (0.7–)1–2.5 cm, (base narrowed gradually to petiole), margins entire. |
Racemes | dense or slightly elongated. |
dense, (elongated in fruit). |
Flowers | sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate); petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade). |
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 | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(ascending, curved to slightly sigmoid), (4–)6–12 mm, (stout). |
Fruits | (pendent or horizontal, sessile or substipitate), subglobose to broadly ellipsoid, not or slightly inflated, (4–)5–8 mm; valves (not retaining seeds after dehiscence), glabrous throughout; replum as wide as or wider than fruit; ovules 4–8(–12) per ovary; style 1–3(–4) 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). |
