blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid.

(proximal often narrowed to short petiole, distal sessile);

blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire.

petiolate, sessile, or subsessile;

blade base usually not auriculate (except Paysonia), margins entire, dentate, or sinuate.

dense or slightly elongated.

ebracteate, often elongated in fruit.

sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate);
