blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.

(erect to prostrate, petiole distinct from blade);

(proximal shortly petiolate, distal usually sessile);

blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire.

blade spatulate, distinctly different from basal.

compact, (± subumbellate to densely corymbiform, elongated or not).
