Flora of North America species comparison

few from base, decumbent, (arising laterally proximal to current season’s leaves), 0.3–0.8 dm.

few to several from base, erect, (from basal leaf cluster, branched distally, flowering branches slender, subtended by bracts), 3–6 dm.

(petiole slender);

blade broadly obovate, or deltate to ovate or narrower, 1.5–3.5 cm, (base abruptly to gradually narrowed to petiole), margins entire or obscurely few-toothed, (apex usually obtuse, nearly acute in narrower leaves).

blade oblanceolate or broadly obovate, to 10 cm, margins usually sinuate-dentate or entire, sometimes lobed.

(2–5 per stem);

blade oblanceolate to spatulate, similar to basal, margins entire, (apex acute).

(proximal shortly petiolate, distal sessile);

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

loose, (3–6-flowered).

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

sepals narrowly oblong to linear, 7–9 mm;

petals (erect), spatulate, 10–12(–15) mm.

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

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

(widely spreading to ascending, slightly curved or straight), 7–11 mm.

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

(usually purplish in age), didymous, irregular and somewhat angular, not highly inflated, 4–11 × 10–13 mm, (coriaceous, papery, shallowly grooved distally and on sides, tapered and narrowed toward replum, base obtuse to truncate, apex with broad sinus to nearly truncate);

valves (retaining seeds after dehiscence), densely pubescent, not silvery;

replum elliptic to obovate, as wide as or wider than fruit, base rounded, margins sparsely pubescent or glabrous, apex rounded (with funicles);

ovules 4 per ovary;

style 5–7 mm, (glabrous).

(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).
