Habit | Perennials; caudex simple, (usually woody); densely pubescent, trichomes (sessile or short-stalked), several-rayed, rays simple or furcate, (smooth or tuberculate). | Annuals or, sometimes, bi-ennials; with a fine taproot; sparsely pubescent, trichomes (sessile), 3–6-rayed, rays furcate, (tuberculate throughout). |
Stems | simple from base, erect, (unbranched, sparsely leaved), to 7 dm. |
several from base, erect or decumbent and straggling, (branched distally, branches usually filiform), to 5 dm. |
Basal leaves | blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid. |
blade obovate or rhombic to broadly elliptic, 1–4.5(–6.5) cm, margins entire or lyrate-pinnatifid. |
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 sessile); blade rhombic or obovate to elliptic, 0.5–2(–3) cm, margins entire or sinuate to remotely toothed. |
Racemes | dense or slightly elongated. |
loose. |
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 or ovate, 2.5–5.5 mm, (median pair thickened apically, cucullate); petals (yellow to orange-yellow), obovate to cuneate, 4–7 mm, (apex sometimes retuse). |
Fruiting pedicels | (spreading or recurved, loosely sigmoid), 5–25 mm. |
(recurved in age), 5–10(–15) mm, (slender). |
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 or subglobose, not or slightly inflated, (2–)3–5(–7) mm; valves (not retaining seeds after dehiscence), glabrous throughout; replum as wide as or wider than fruit; ovules (4–)8–16(–20) per ovary; style (1–5–)2–4.5 mm. |
Seeds | flattened. |
