Flora of North America species comparison

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

several from base, erect to decumbent, (unbranched, fertile stems from among basal leaves), 1.2–1.8 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.

(erect, not rosulate);

blade broadly oblanceolate, 4–8 cm, margins entire or shallowly sinuate-dentate, (apex acute).

(proximal petiolate, distal sessile);

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

(proximal petiolate);

blade narrowly lanceolate, similar to basal in size, (distal with cuneate base), margins entire.

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

loose, (elongated in fruit).

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 (greenish yellow), elliptic, often broadly so, 4.8–7.1 mm;

petals oblanceolate, 6.8–9.8 mm.

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

(widely spreading to recurved), 1–1.5 cm.

(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.

(usually pendent), slightly didymous apically, obcordate, slightly inflated, 4–7 × 3–6 mm, (papery, basal sinus absent, apical sinus evident to nearly absent);

valves (retaining seeds after dehiscence), pubescent;

replum broadly obovate to suborbicular, 4–5 mm, as wide as or wider than fruit, margins entire;

ovules usually 4 (rarely 6–8) per ovary;

style (2.5–)3–4(–5) mm.

flattened (sometimes slightly).

plump.
