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.

several (to several hundred) from base, erect, (each terminating in a tufted cluster of leaves), to 7 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).

(petiole not differentiated from blade);

blade narrowly elliptic to narrowly linear-oblanceolate, (0.8–)1–1.5 cm, (base cuneate), margins entire.

(usually secund);

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

similar to basal, blade sometimes linear, (apex acute).

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

dense, (often ± subumbellate, somewhat elongated in fruit).

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 narrowly elliptic, 2.5–3.5(–4) mm, (not keeled);

petals narrowly spatulate, 4–7 mm.

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

(strongly sigmoid), 5–10 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.

ellipsoid, compressed, 4–6 mm;

valves densely pubescent, trichomes appressed;

ovules 2 per ovary;

style 2–3.5 mm.

somewhat flattened.

flattened, (oval).
