Flora of North America species comparison

several from base, usually decumbent to ascending, (arising laterally, unbranched, coarse), 1–2 dm.

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

blade pandurate or obovate, 3–6 cm, margins usually deeply and broadly incised, rarely subentire, (apex obtuse).

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

blade oblanceolate to spatulate, similar to basal, (3–6 mm wide), margins entire, (apex often somewhat acute).

(proximal shortly petiolate, distal sessile);

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

congested, (elongated in fruit).

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

sepals oblong, 6–8 mm;

petals spatulate, to 10 mm.

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

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

(usually curving upward, sigmoid), 6–10 mm.

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

didymous, irregular in shape, somewhat angular, inflated, 5–7 × 6–8 mm, (papery, often rigid, base obtuse or truncate, apical sinus broad, open and deep);

valves (retaining seeds after dehiscence), pubescent, trichomes spreading, loose;

replum oblong, often constricted, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style 5–7 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;
