Flora of North America species comparison

few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm.

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

blade suborbicular to narrowly or broadly oblanceolate to broadly elliptic or rhombic, (1.2–)2–6(–8) cm, (base usually abruptly narrowed to petiole), margins entire, sinuate, or lobed.

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

(proximal petiolate, distal sessile);

blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire.

(proximal shortly petiolate, distal sessile);

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

(usually not secund), dense, (sometimes elongated in fruit).

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

sepals lanceolate, 4–6(–7) mm;

petals (yellow, cream-yellow, cream-white, or white), obovate to oblanceolate, 6–13 mm, (claw weakly differentiated 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).

(erect to divaricate-ascending or recurved, erect in distal 1/3, usually sigmoid, sometimes straight or slightly curved), 4.5–10(–15) mm.

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

(sessile or substipitate), subglobose, obovoid, or ellipsoid, compressed (sometimes slightly angustiseptate), 3–9 mm, (rigid, apex truncate, retuse, or rounded-acute);

valves sparsely or densely pubescent, sometimes sparsely pubescent inside; (septum sometimes fenestrate, perforate, or obsolete);

ovules 4–16 per ovary;

style 1–9 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 (sometimes slightly).
