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, (woody); densely pubescent, trichomes (appressed, except spreading on pedicels and fruits, sessile or short-stalked), several-rayed, rays furcate or bifurcate, (strongly tuberculate throughout). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
few from base, erect, (stout), to 1.5 dm (sometimes greatly reduced). |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade suborbicular to rhombic or broadly elliptic, 1–4.5 cm, margins entire, (apex rounded to subacute). |
Cauline leaves | (proximal often narrowed to short petiole, distal sessile); blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire. |
(proximal petiolate, distal subsessile); blade elliptic, 1–4 cm, (distal narrower), margins entire or remotely dentate. |
Racemes | dense or slightly elongated. |
condensed, (subcorymbose to subumbellate, few-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 (persistent), broadly ovate or oblong to narrowly elliptic, 5.5–8(–9.5) mm, (lateral pair slightly cucullate, median pair thickened apically, cucullate, usually keeled); petals (orange to yellow), oblong to obovate, 8–11.5(–14.5) mm, (slightly narrowed to broad claw, margins sinuate, often retuse). |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(horizontal or divaricate-ascending, straight or slightly curved), 5–15 mm, (stout and rigid). |
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. |
(sessile or substipitate), globose, ovoid, or suborbicular, compressed (with marginal and apical constriction), 4–7 mm; valves pubescent, trichomes contiguous or overlapping, often spreading; ovules 16–24 per ovary; style 2–4 mm. |
Seeds | flattened. |
lenticular, ovate in outline. |
