Flora of North America species comparison

simple from base, erect, (arising from a condensed rosette), to 1 dm.

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

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

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

(1–5);

blade oblanceolate, 1–2.5 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).

compact (or elongated in fruit, to 1 dm, barely exceeding leaves).

loose to somewhat dense.

sepals (erect), oblong to linear or spatulate, 5.5–7 mm;

petals spatulate, 10–14 mm, (claw undifferentiated 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).

(divaricate-ascending, slightly curved), 7–18 mm.

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

didymous, irregular, highly inflated, 8–11(–18) × 10–15 mm, (papery, basal sinus shallower than the deep apical sinus; valves retaining seeds after dehiscence);

replum obovate, not constricted, 1–1.8 mm, apex obtuse, as wide as or wider than fruit;

ovules (4–)8(–12) per ovary;

style 4–6 mm, (glabrous).

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, (oblong to elliptic, thin-margined or not).

flattened.
