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

few to several from base, erect or outer ones decumbent, 0.5–4 dm.

(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).

(long-petiolate);

blade elliptic to obovate or rhombic, 2–6(–9) cm, margins entire.

(2–5 per stem);

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

(sessile or shortly petiolate);

blade oblanceolate to spatulate, 1–3 cm, (proximal broader), margins entire.

loose, (3–6-flowered).

dense, (relatively short).

sepals narrowly oblong to linear, 7–9 mm;

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