Flora of North America species comparison

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

(petiole somewhat winged);

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

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

(usually secund);

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

moderately dense (or elongated).

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

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

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).

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

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

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.

plump, (broad).

somewhat flattened.
