Flora of North America species comparison

several from base, usually somewhat decumbent, (unbranched), (0.4–)0.5–2 dm.

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

(petiole slender, often narrowly winged);

blade obovate to orbicular or rhombic-orbicular, 2–9 cm, (base abruptly narrowed to petiole), margins usually entire, rarely with few scattered teeth, (apex rounded or obtuse, sometimes with apical mucro).

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 spatulate to oblanceolate, 1–3 cm, margins entire, (apex usually obtuse).

(proximal petiolate, distal sessile);

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

loose, (elongated in fruit).

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

sepals linear-oblong, 4–7.5 mm;

petals spatulate, 6–11 mm.

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).

(divaricate, slightly sigmoid or nearly straight), 6–12 mm.

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

(erect), didymous, suborbicular, inflated, (4–)6–15 × (4–)8–20 mm, (papery, basal and apical sinuses similar, basal rarely shallower, apical deep, narrow and closed or nearly so);

valves retaining seeds after dehiscence, pubescent, trichomes appressed;

replum oblong, constricted, 2–3.5 mm, narrower than fruit, apex obtuse;

ovules (2 or) 4 per ovary;

style 4–6(–9) mm.

(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.

(dark brown), flattened, (2–3 mm).

flattened (sometimes slightly).
