several from base, decumbent to ascending, (unbranched), 0.5–1.5 dm.

several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 4 dm.

(petiole slender);

blade obovate, 3–5 cm (width 10–20 mm, base tapering abruptly to petiole), margins entire, (apex rarely slightly acute).

blade obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate.

(proximal usually shortly petiolate, distal sessile);

blade obovate to broadly elliptic, 1–3 cm, margins sinuate or shallowly toothed.

subcorymbose.

dense, compact, (elongated in fruit).

sepals oblong, 8–10 mm;

petals spatulate, 12–14 mm.
