(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).

similar to basal, blade oblanceolate or narrowly oblong, reduced in size, (base gibbous).

(2–5 per stem);
