Flora of North America species comparison

several from base, erect or lateral decumbent, (unbranched), 1–2 dm.

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

(petiole usually winged);

blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded).

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

blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute).

(proximal shortly petiolate, distal sessile);

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

loose (and greatly elongated in fruit) to congested.

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

sepals linear-oblong, 5–7 mm;

petals spatulate, 9–11 mm.

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

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

(recurved), 6–15 mm.

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

(usually pendent on arching pedicels, less frequently widely divergent), irregular in shape, (base obtuse or slightly cordate, apex deeply and broadly notched), not strongly inflated, 8–11 × 8–12 mm, (papery);

valves retaining seeds after dehiscence;

replum linear-oblong, constricted, 2.5–4 mm, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style 5–8 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.
