Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | Perennials; caudex branched, (thickened, cespitose); densely pubescent, trichomes 5- or 6-rayed, rays slightly fused at base, furcate or bifurcate, (tuberculate throughout). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded). |
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 spatulate, margins entire. |
Racemes | dense or slightly elongated. |
compact, subumbellate. |
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 (pale yellow), 4–5 mm; petals lingulate, 6–7 mm. |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(ascending, curved to slightly sigmoid), 5–8 mm. |
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. |
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. |
plump. |
