Flora of North America species comparison

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

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

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

(proximal petiolate, distal sessile);

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

(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).

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

loose to somewhat dense.

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 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).

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

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

(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.

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.

flattened (sometimes slightly).

flattened.
