Flora of North America species comparison

simple from base, erect, (unbranched, sparsely leaved), to 7 dm.

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

blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid.

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

(proximal often narrowed to short petiole, distal sessile);

blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire.

(proximal shortly petiolate, distal sessile);

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

dense or slightly elongated.

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

sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate);

petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade).

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

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

(spreading or recurved, loosely sigmoid), 5–25 mm.

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

(pendent or horizontal, sessile or substipitate), subglobose to broadly ellipsoid, not or slightly inflated, (4–)5–8 mm;

valves (not retaining seeds after dehiscence), glabrous throughout;

replum as wide as or wider than fruit;

ovules 4–8(–12) per ovary;

style 1–3(–4) 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).

flattened.
