Flora of North America species comparison

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

simple from base, erect to decumbent, (well-exserted beyond basal leaves, loosely spreading), 0.3–1.2 dm.

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

(erect to prostrate, petiole distinct from blade);

blade (inner) spatulate to oblanceolate, or (outer) oblanceolate or orbicular, 1.5–4 cm, margins entire (rarely folded).

(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 spatulate, distinctly different from basal.

loose to somewhat dense.

moderately dense, (6–20-flowered).

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 (pale yellow), elliptic, 3.5–5 mm;

petals lingulate, 6–9 mm.

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

(strongly sigmoid), 10–20 mm (2 times longer than fruits).

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.

lanceolate or orbicular, slightly inflated, (2.5–)3–6 mm, (apex usually strongly narrowed);

valves pubescent, trichomes sparse and closely appressed to surface;

ovules 4–8 per ovary;

style 2.5–6 mm (usually ± equal in length to mature fruit).

flattened.
