Flora of North America species comparison

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

few from base, decumbent, (arising laterally proximal to current season’s leaves), 0.3–0.8 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).

(petiole slender);

blade broadly obovate, or deltate to ovate or narrower, 1.5–3.5 cm, (base abruptly to gradually narrowed to petiole), margins entire or obscurely few-toothed, (apex usually obtuse, nearly acute in narrower leaves).

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

(2–5 per stem);

blade oblanceolate to spatulate, similar to basal, margins entire, (apex acute).

moderately dense (or elongated).

loose, (3–6-flowered).

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

sepals narrowly oblong to linear, 7–9 mm;

petals (erect), spatulate, 10–12(–15) mm.

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