Flora of North America species comparison

several from base, decumbent to ascending (arising laterally, unbranched, stout), (0.2–)0.5–1.7 dm.

few to several from base, erect or outer decumbent, 0.5–2.5 dm.

(petiole somewhat winged);

blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy).

blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.

blade oblanceolate to broadly spatulate, 1–2 cm (width 3–5 mm), margins entire, (apex obtuse to subacute).

(proximal shortly petiolate, distal usually sessile);

blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire.

moderately dense (or elongated).

compact, (± subumbellate to densely corymbiform, elongated or not).

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically);

petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated).

(divergent, straight to somewhat curved or sigmoid), 5–12 mm.

(usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout).

(erect), didymous, cordate, moderately inflated, (6–)10–20 × 10–23 mm, (papery, base obtuse or with obscure sinus, apical sinus deep, broad);

valves (retaining seeds after dehiscence), densely and loosely pubescent, trichomes spreading;

replum linear-oblong, constricted, as wide as or wider than fruit;

ovules 4 per ovary;

style 4–5(–9) mm.

(sessile or shortly stipitate, less than 1 mm), subglobose to broadly ellipsoid, inflated or slightly compressed (terete or subterete), (4–)5–8(–9) mm;

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;

ovules 8–16 per ovary;
