Flora of North America species comparison

several from base, usually somewhat decumbent, (unbranched), (0.4–)0.5–2 dm.

simple from base, prostrate, (arising lateral to rosette), 0.1–0.5 dm.

(petiole slender, often narrowly winged);

blade obovate to orbicular or rhombic-orbicular, 2–9 cm, (base abruptly narrowed to petiole), margins usually entire, rarely with few scattered teeth, (apex rounded or obtuse, sometimes with apical mucro).

blade suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed).

blade spatulate to oblanceolate, 1–3 cm, margins entire, (apex usually obtuse).

(2–4);

blade oblanceolate, ca. 1 cm, (base cuneate), margins entire, (apex acute).

loose, (elongated in fruit).

condensed.

sepals linear-oblong, 4–7.5 mm;

petals spatulate, 6–11 mm.

sepals (erect, purplish to greenish), linear-oblong or boat-shaped, 5.5–6.5 mm, (lateral pair more saccate than median);

petals (white), spatulate, 9–12 mm, (claw undifferentiated from blade).

(divaricate, slightly sigmoid or nearly straight), 6–12 mm.

(divaricate-ascending, nearly straight), 6–10 mm.

(erect), didymous, suborbicular, inflated, (4–)6–15 × (4–)8–20 mm, (papery, basal and apical sinuses similar, basal rarely shallower, apical deep, narrow and closed or nearly so);

valves retaining seeds after dehiscence, pubescent, trichomes appressed;

replum oblong, constricted, 2–3.5 mm, narrower than fruit, apex obtuse;

ovules (2 or) 4 per ovary;

style 4–6(–9) mm.

strongly didymous, irregular in shape and size, (base slightly cordate, apex with a deep closed sinus), strongly to somewhat inflated, 6–8 × 6–8 mm (± bladderlike, papery);

valves (retaining seeds after dehiscence), pubescent;

replum elliptic to obovate, not constricted, as wide as or wider than fruit, apex obtuse;

ovules 4–8 per ovary;

style 4–5 mm, (sparsely pubescent or glabrous).
