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, (sometimes woody at base); densely (silvery) pubescent, trichomes (sessile or short-stalked), several-rayed, rays not furcate, fused (webbed) ca. 1/2 their length, (tuberculate throughout or tubercles scarce or absent over center). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate. |
Cauline leaves | (proximal often narrowed to short petiole, distal sessile); blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire. |
(shortly petiolate); blade usually linear to narrowly oblanceolate, rarely elliptic to rhombic, 0.5–2.5 cm, (base narrowing to petiole), margins entire or remotely dentate (sometimes involute). |
Racemes | dense or slightly elongated. |
loose to somewhat dense. |
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 elliptic to oblong, 5–8 mm, (lateral pair not saccate, median pair often thickened apically, ± cucullate); petals (usually orange or orange-yellow at junction of blade and claw, sometimes also with orange guidelines), obdeltate to obovate, 8–12 mm, (claw relatively short). |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(divaricate-spreading to erect, usually straight or slightly curved, occasionally sigmoid), 8–20(–40) 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. |
globose, broadly ellipsoid, or ovoid, not or slightly inflated, 5–8 mm, (firm, apex usually acute); valves (not retaining seeds after dehiscence, often reddish in age), glabrous throughout; replum as wide as or wider than fruit; ovules (12–)20–32(–40) per ovary; style (2–)3–6 mm. |
Seeds | flattened. |
