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, prostrate, (arising lateral to rosette), 0.1–0.5 dm.

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

blade suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed).

(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).

(2–4);

blade oblanceolate, ca. 1 cm, (base cuneate), margins entire, (apex acute).

loose to somewhat dense.

condensed.

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 (erect, purplish to greenish), linear-oblong or boat-shaped, 5.5–6.5 mm, (lateral pair more saccate than median);

petals (white), spatulate, 9–12 mm, (claw undifferentiated from blade).

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

(divaricate-ascending, nearly straight), 6–10 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.

strongly didymous, irregular in shape and size, (base slightly cordate, apex with a deep closed sinus), strongly to somewhat inflated, 6–8 × 6–8 mm (± bladderlike, papery);

valves (retaining seeds after dehiscence), pubescent;

replum elliptic to obovate, not constricted, as wide as or wider than fruit, apex obtuse;

ovules 4–8 per ovary;

style 4–5 mm, (sparsely pubescent or glabrous).
