Flora of North America species comparison

several from base, prostrate, (slender, sparsely pubescent), 0.5–2 dm.

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

blade obovate to narrowly elliptic, 1.5–6 cm, margins usually entire, rarely shallowly dentate, (surfaces densely pubescent, often silvery).

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).

blade oblanceolate to spatulate, 0.5–1 cm, margins entire, (surfaces often sparsely pubescent).

(usually secund);

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

(narrow), loose, (elongated in fruit).

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

sepals (greenish brown, sometimes magenta), linear or elliptic, 4.3–6(–7.5) mm, (median pair thickened apically, cucullate);

petals (frequently pink or magenta in distal 1/3–1/2), spatulate to oblanceolate, 6–10(–12) mm, (claw undifferentiated from blade).

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).

(ascending to somewhat spreading, straight to slightly curved), 4–8(–12) mm.

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

broadly ovoid to suborbicular, inflated, (terete or, often, slightly angustiseptate), 3–6mm;

valves sparsely pubescent;

ovules usually 4, rarely 6–8 per ovary;

style 3–6.5 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.
