Flora of North America species comparison

several from base, decumbent to ascending (arising laterally, unbranched, stout), (0.2–)0.5–1.7 dm.

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

(petiole somewhat winged);

blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy).

(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.

blade oblanceolate to broadly spatulate, 1–2 cm (width 3–5 mm), margins entire, (apex obtuse to subacute).

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

moderately dense (or elongated).

compact (or elongated in fruit, to 1 dm, barely exceeding leaves).

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

sepals (erect), oblong to linear or spatulate, 5.5–7 mm;

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

(divergent, straight to somewhat curved or sigmoid), 5–12 mm.

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

(erect), didymous, cordate, moderately inflated, (6–)10–20 × 10–23 mm, (papery, base obtuse or with obscure sinus, apical sinus deep, broad);

valves (retaining seeds after dehiscence), densely and loosely pubescent, trichomes spreading;

replum linear-oblong, constricted, as wide as or wider than fruit;

ovules 4 per ovary;

style 4–5(–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).

plump, (broad).

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