Flora of North America species comparison

several from base, decumbent to ascending (arising laterally, unbranched, stout), (0.2–)0.5–1.7 dm.

few from base, erect, (stout), to 1.5 dm (sometimes greatly reduced).

(petiole somewhat winged);

blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy).

blade suborbicular to rhombic or broadly elliptic, 1–4.5 cm, margins entire, (apex rounded to subacute).

blade oblanceolate to broadly spatulate, 1–2 cm (width 3–5 mm), margins entire, (apex obtuse to subacute).

(proximal petiolate, distal subsessile);

blade elliptic, 1–4 cm, (distal narrower), margins entire or remotely dentate.

moderately dense (or elongated).

condensed, (subcorymbose to subumbellate, few-flowered).

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

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).

(divergent, straight to somewhat curved or sigmoid), 5–12 mm.

(horizontal or divaricate-ascending, straight or slightly curved), 5–15 mm, (stout and rigid).

(erect), didymous, cordate, moderately inflated, (6–)10–20 × 10–23 mm, (papery, base obtuse or with obscure sinus, apical sinus deep, broad);

valves (retaining seeds after dehiscence), densely and loosely pubescent, trichomes spreading;

replum linear-oblong, constricted, as wide as or wider than fruit;

ovules 4 per ovary;

style 4–5(–9) 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.

plump, (broad).

lenticular, ovate in outline.
