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

simple from base, erect, (arising from a condensed rosette), to 1 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).

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

(2–5 per stem);

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

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

loose, (3–6-flowered).

compact (or elongated in fruit, to 1 dm, barely exceeding leaves).

sepals narrowly oblong to linear, 7–9 mm;

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

sepals (erect), oblong to linear or spatulate, 5.5–7 mm;
