(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).

(petiole 1–3.5 cm);

blade ovate to rhombic or rotund, 2–7 cm, (base narrowed abruptly to petiole), margins usually entire, occasionally shallowly repand, (flat).

(2–5 per stem);

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

blade elliptic or narrowly so, (0.7–)1–2.5 cm, (base narrowed gradually to petiole), margins entire.

loose, (3–6-flowered).

dense, (elongated in fruit).

sepals narrowly oblong to linear, 7–9 mm;
