Flora of North America species comparison

few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm.

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

blade suborbicular to narrowly or broadly oblanceolate to broadly elliptic or rhombic, (1.2–)2–6(–8) cm, (base usually abruptly narrowed to petiole), margins entire, sinuate, or lobed.

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

(proximal petiolate, distal sessile);

blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire.

(proximal petiolate, distal subsessile);

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

(usually not secund), dense, (sometimes elongated in fruit).

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

sepals lanceolate, 4–6(–7) mm;

petals (yellow, cream-yellow, cream-white, or white), obovate to oblanceolate, 6–13 mm, (claw weakly differentiated from blade).

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).

(erect to divaricate-ascending or recurved, erect in distal 1/3, usually sigmoid, sometimes straight or slightly curved), 4.5–10(–15) mm.

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

(sessile or substipitate), subglobose, obovoid, or ellipsoid, compressed (sometimes slightly angustiseptate), 3–9 mm, (rigid, apex truncate, retuse, or rounded-acute);

valves sparsely or densely pubescent, sometimes sparsely pubescent inside; (septum sometimes fenestrate, perforate, or obsolete);

ovules 4–16 per ovary;

style 1–9 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.

flattened (sometimes slightly).
