several from base, erect or lateral decumbent, (unbranched), 1–2 dm.

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

(petiole usually winged);

blade broadly oblanceolate, 3–8 cm, margins usually dentate or pinnatifid, rarely subentire, (terminal lobe acute or obtuse, not rounded).

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

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

blade spatulate to linear-oblanceolate, 1–3 cm, margins usually entire, rarely toothed, (apex acute).

dense or slightly elongated.

loose (and greatly elongated in fruit) to congested.

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