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, (densely cespitose and forming hemispheric mounds); densely pubescent, trichomes 5-rayed, rays bifurcate near base, fused at base, (strongly tuberculate throughout). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
few to several from base, erect, (usually exceeding basal leaves), 0.3–0.7 dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade linear-spatulate, 1.5–4 cm, (base narrowed gradually to petiole), margins entire. |
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, similar to basal. |
Racemes | dense or slightly elongated. |
crowded in distal 1/3, (4–10-flowered). |
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), oblong to elliptic, 3–4 mm, (median pair usually thickened apically, cucullate); petals (sometimes with slight tinge of orange basally), lingulate, 4–6 mm. |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(loosely to strongly sigmoid), 6–10 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. |
ellipsoid, slightly inflated (somewhat latiseptate), 4–5 mm, (apex acute); valves pubescent, trichomes erect, appearing slightly shaggy; ovules 4–8 per ovary; styles 2.5–3 mm, (shorter than mature fruits). |
Seeds | flattened. |
± flattened, convex on outer side. |
