Flora of North America species comparison

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

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

(2–5 per stem);

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

(proximal usually shortly petiolate, distal sessile);

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

loose, (3–6-flowered).

dense, compact, (elongated in fruit).

sepals narrowly oblong to linear, 7–9 mm;

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

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

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

(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).

(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.

flattened.
