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, (from basal leaf cluster, branched distally, flowering branches slender, subtended by bracts), 3–6 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 oblanceolate or broadly obovate, to 10 cm, margins usually sinuate-dentate or entire, sometimes lobed.

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

(proximal shortly petiolate, distal sessile);

blade oblanceolate to narrowly oblong, similar to basal, (distal with base slightly cuneate).

moderately dense (or elongated).

paniculate, (rachises and pedicels more densely pubescent than proximal leaves).

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

sepals elliptic, 3–7 mm, (median pair slightly thickened apically, cucullate);

petals (white), broadly ovate, to 12 mm, (narrowing gradually to short claw).

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

(widely divaricate-ascending and straight, or slightly recurved), 10–15 mm, (slender, pubescent).

(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.

(widely spreading to nearly pendent in age, shortly stipitate), globose or subglobose, not or slightly inflated, 3–10 mm;

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;

ovules 8–12 per ovary;

style ca. 2 mm, (slender, fragile).

plump, (broad).

flattened.
