several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm.

simple from base, prostrate to decumbent, (unbranched, from within and below leaf clusters, slender), 0.2–0.8 dm.

blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate.

(tufted, erect or ascending, silvery);

blade linear to oblanceolate or (outer) oblanceolate to obovate or rhombic, 1.5–3.3 cm, (base sometimes subhastate), margins entire or dentate, (often involute).

(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).

blade nearly linear, to 1.5 cm, margins entire.

loose to somewhat dense.

dense, (subcorymbose).

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).

sepals (yellow-green), lanceolate, (2.5–)3.5–4.5 mm;

petals spatulate to oblanceolate, 4–6.5 mm.

(divaricate-spreading to erect, usually straight or slightly curved, occasionally sigmoid), 8–20(–40) mm.

(recurved), 5–8 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.

(usually pendent), obdeltate, compressed (angustiseptate), 2–4 mm, (wider than long, base tapered to acute angle, apex truncate with inflated shoulders);

valves densely pubescent; (septum obsolete or with a narrow fringe inside of replum, funicles attached close to replum apex);
