Flora of North America species comparison

several from base, decumbent, (unbranched, leafy for the genus), ca. 1 dm.

simple or several from base, prostrate to erect, 0.5–2(–3.5) dm.

(forming a strong rosette; long-petiolate);

blade obovate, 1.5–4(–8) cm, (base ± abruptly narrowing to petiole), margins usually repand or dentate, rarely entire, (apex usually angular, surfaces silvery).

blade suborbicular or obovate to elliptic, (1–)2–5(–7) cm, margins entire, sinuate, or shallowly dentate.

blade oblanceolate, 1–2 cm (width 4–8 mm), margins entire or with occasional tooth, (apex acute).

(often secund, proximal shortly petiolate, distal sessile);

blade linear to obovate or rhombic, 1–2.5(–4) cm, margins entire or shallowly dentate.

congested, (elongated in fruit, greatly exceeding leaves).

dense, compact, (usually elongated in fruit).

sepals lanceolate to oblong, 6–8 mm, (often keeled);

petals spatulate, 10–12 mm.

sepals elliptic, 5–8.5 mm, (lateral pair boat-shaped, saccate, median pair thickened apically, cucullate);

petals (yellow to orange, sometimes fading purplish), narrowly spatulate or obovate, (6–)7.5–12 mm, (claw undifferentiated from blade, or gradually narrowed to claw, slightly expanded basally).

(spreading, straight or slightly curved), 8–12 mm.

(usually sharply sigmoid, rarely nearly divaricate-spreading and straight), 5–15(–20) mm, (stout).

(erect), didymous, inflated, 10–20 × 10–20 mm, (papery or firm, basal sinus shallow to deep, sometimes barely notched, apical sinus deep, narrow, usually closed);

valves (retaining seeds after dehiscence), loosely pubescent, trichomes spreading (appearing fuzzy);

replum obovate to broadly oblong, not constricted, 3–4 mm, as wide as or wider than fruit, apex obtuse;

ovules (4–)8 per ovary;

style 7–9 mm.

(erect), ellipsoid or ovoid, not or slightly obcompressed, (apex not compressed), (6–)7–12 mm;

valves densely pubescent, sometimes sparsely pubescent inside;

ovules (8–)12–20(–24) per ovary;

style 3–7 mm, (sometimes pubescent).
