Habit | Annuals or biennials; (delicate, wiry); with a fine taproot; pubescent, trichomes (sessile or subsessile), 4–7-rayed, rays distinct, usually furcate, occasionally bifurcate, (smooth to somewhat tuberculate). | Perennials; (delicate, short-lived); caudex simple, (sometimes elongated, covered with persistent leaf bases); usually sparsely pubescent, trichomes 7–12-rayed, rays furcate near base. | ||||
Stems | simple to several from base, erect, often outer decumbent, (unbranched or branched distally), 1–7 dm. |
simple from base, erect to decumbent, (unbranched, mostly filiform, slender), 1–1.5 dm. |
||||
Basal leaves | blade oblanceolate to elliptic, 1.5–8(–11.5) cm, margins lyrate-pinnatifid to dentate or repand, (abaxial surface densely pubescent, adaxial sparsely pubescent). |
(erect, petiole slender); blades broadly ovate to elliptic, 0.5–1 cm, (base abruptly narrowing to petiole), margins entire. |
||||
Cauline leaves | (proximal petiolate, distal sessile); blade oblanceolate to oblong, 1–7 cm, margins dentate to repand. |
(remote, distally shortly petiolate); blade ± spatulate, (base cuneate), margins entire. |
||||
Racemes | loose, (elongated). |
lax, (elongated, few-flowered). |
||||
Flowers | sepals elliptic or broadly ovate, 3–6.5(–8) mm, (median pair slightly thickened apically, cucullate); petals (yellow to orange), broadly obovate, 6–11 mm, (narrowing gradually to short claw). |
sepals (erect), oblong, 3.5–4 mm, (lateral pair not saccate); petals (often fading to light purple apically), spatulate to nearly lingulate, 6–7 mm. |
||||
Fruiting pedicels | (usually divaricate-spreading, sometimes horizontal or shallowly recurved, straight or slightly curved), (7–)10–20(–25) mm, (slender or stout). |
(recurved to widely spreading, filiform, slender), 5–10 mm. |
||||
Fruits | (stipitate or subsessile, gynophore 1–2 mm), globose, subglobose, obpyriform, or obovoid, not or slightly inflated, 3–9 mm; valves (not retaining seeds after dehiscence), glabrous throughout or sparsely pubescent inside; replum as wide as or wider than fruit; ovules 8–20(–28) per ovary; style 2–4.5 mm. |
(pendent), globose or subglobose, compressed, 3–4 mm; valves ± densely pubescent; ovules 6–10 per ovary; style ca. 1.5 mm. |
