Habit | Annuals or, sometimes, bi-ennials; with a fine taproot; sparsely pubescent, trichomes (sessile), 3–6-rayed, rays furcate, (tuberculate throughout). | Perennials; caudex simple, (with deep roots, thickened); densely (silvery) pubescent throughout (densely covering leaves with several appressed layers), less dense on stems, trichomes (stellate-scalelike), rays fused (webbed) in proximal 1/2 or to tips, (umbonate, nearly smooth to moderately tuberculate). | ||||
Stems | several from base, erect or decumbent and straggling, (branched distally, branches usually filiform), to 5 dm. |
simple from base, erect or outer ones slightly decumbent toward base, (from below or in basal leaves, unbranched), (0.5–)0.8–1.6(–2) dm. |
||||
Basal leaves | blade obovate or rhombic to broadly elliptic, 1–4.5(–6.5) cm, margins entire or lyrate-pinnatifid. |
(erect, petiole long, slender); blade spatulate to broadly oblanceolate, (3–)5–7(–12) cm, (base gradually tapering to petiole), margins entire, (apex rounded or obtuse). |
||||
Cauline leaves | (proximal petiolate, distal sessile); blade rhombic or obovate to elliptic, 0.5–2(–3) cm, margins entire or sinuate to remotely toothed. |
blade oblanceolate, similar to basal, (base cuneate), margins entire. |
||||
Racemes | loose. |
dense. |
||||
Flowers | 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). |
sepals (erect), linear to linear-oblong, somewhat boat-shaped, 7–10 mm; petals (erect at anthesis), lingulate, 11–15 mm, (claw undifferentiated from blade). |
||||
Fruiting pedicels | (recurved in age), 5–10(–15) mm, (slender). |
(divaricate-ascending, straight or slightly curved), 10–15 mm. |
||||
Fruits | 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. |
(purplish in age), strongly didymous, semiorbicular, highly inflated, 10–18 × 14–19 mm, (papery), basal sinus usually shallow, rarely absent, apical sinus deep, narrowly V-shaped; valves retaining seeds after dehiscence, sides flat, back rounded, margins keeled, base and apex obtuse; replum narrowly oblong to linear, as wide as or wider than fruit, base slightly narrowed, apex obtusely rounded; ovules 4 per ovary; style 3–5 mm, (slender). |
||||
Seeds | flattened. |
slightly flattened. |
