Flora of North America species comparison

several from base, erect or lateral decumbent, (unbranched), 1–2 dm.

several from base, decumbent to ascending, (arising laterally beneath a dense rosette), less than 0.1 dm.

(petiole usually winged);

blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded).

(petiole slender);

blade (horizontal on the ground), obovate, 0.5–1.5 cm (width 4–8 mm, base tapering abruptly to petiole), margins entire, (apex usually acute, surfaces silvery from a dense incrustation of appressed, stellate trichomes).

blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute).

blade oblanceolate, 0.5–1 cm (width 2–3 mm), margins entire, (surfaces densely stellate pubescent).

loose (and greatly elongated in fruit) to congested.

congested, (subumbellate, often almost sessile, barely exceeding basal leaves).

sepals linear-oblong, 5–7 mm;

petals spatulate, 9–11 mm.

sepals (yellowish green), narrowly lanceolate, 4–5 mm;

petals (erect), oblanceolate, 6–7 mm, (claw weakly differentiated from blade).

(recurved), 6–15 mm.

(divaricate, straight), 5–10 mm.

(usually pendent on arching pedicels, less frequently widely divergent), irregular in shape, (base obtuse or slightly cordate, apex deeply and broadly notched), not strongly inflated, 8–11 × 8–12 mm, (papery);

valves retaining seeds after dehiscence;

replum linear-oblong, constricted, 2.5–4 mm, as wide as or wider than fruit, apex obtuse;

ovules 4 per ovary;

style 5–8 mm.

didymous, ovate, inflated, 4.8–6 × 6–10 mm, (papery, basal and apical sinuses deep);

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

replum obovate, 3–4 mm, as wide as or wider than fruit;

ovules 8 per ovary (2–4 abortive);
