Flora of North America species comparison

few to several from base, ascending or prostrate, (arising laterally, also from within basal leaves, usually unbranched, rarely branched), 0.5–3(–6) dm.

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

blade narrowly oblanceolate or broadly elliptic, 1–7(–12) cm, margins entire or shallowly toothed, sometimes repand, (inner blades usually flattened in age, surfaces often gray-green, scabrous).

(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.

(usually secund);

blade spatulate or obovate, 1–2.5(–4.5) cm, margins entire or shallowly toothed, (flat or involute).

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

somewhat crowded (to moderately elongated in fruit, exceeding basal leaves).

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

sepals broadly elliptic or oblong, 4–7.5(–9) mm, (median pair thickened apically, cucullate);

petals cuneate or obovate, 7–10(–16) mm, (tapering gradually to broad claw).

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

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

(often divaricate-spreading and straight, or horizontal and loosely sigmoid, sometimes slightly recurved), 5–15 mm.

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

subglobose to ovoid or ellipsoid, sometimes compressed, (4–)5–7(–9) mm;

valves sparsely pubescent, trichomes appressed or erect, sometimes sparsely pubescent inside;

ovules (8–)12–16(–20) per ovary;

style 2–7 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).

somewhat flattened.

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