Flora of North America species comparison

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

several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 4 dm.

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

blade obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate.

(proximal shortly petiolate, distal sessile);

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

(proximal usually shortly petiolate, distal sessile);

blade obovate to broadly elliptic, 1–3 cm, margins sinuate or shallowly toothed.

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

dense, compact, (elongated in fruit).

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

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

sepals elliptic or narrowly elliptic or oblong, (3.8–)4.5–5.5 mm, (lateral pair cucullate, very convex, median pair tapering to base, thickened apically, cucullate, often slightly keeled);

petals cuneate, 6.5–8 mm, (slightly expanded at base, margins sinuate, apex retuse or entire).

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

(recurved, curved or sigmoid), somewhat expanded apically.

(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).

(sessile or substipitate), oblong or broadly elliptic, compressed (latiseptate), 5–8 mm;

valves pubescent, trichomes spreading, sparsely pubescent inside;

ovules 4–6 per ovary;

style 3–5 mm.
