Flora of North America species comparison

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

simple from base, erect, (arising from a condensed rosette), to 1 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.

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

(proximal petiolate, distal sessile);

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

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

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

compact (or elongated in fruit, to 1 dm, barely exceeding 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 (erect), oblong to linear or spatulate, 5.5–7 mm;

petals spatulate, 10–14 mm, (claw undifferentiated from blade).

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

(divaricate-ascending, slightly curved), 7–18 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.

didymous, irregular, highly inflated, 8–11(–18) × 10–15 mm, (papery, basal sinus shallower than the deep apical sinus; valves retaining seeds after dehiscence);

replum obovate, not constricted, 1–1.8 mm, apex obtuse, as wide as or wider than fruit;

ovules (4–)8(–12) per ovary;

style 4–6 mm, (glabrous).

flattened (sometimes slightly).

flattened, (oblong to elliptic, thin-margined or not).
