1–5 from base, prostrate to slightly decumbent, (arising laterally, also erect or ascending from tuft of basal leaves, unbranched, purple-green), 0.08–0.3 dm.

blade obovate to broadly oblong, 1.5–5(–8) cm, margins lyrate-pinnatifid, dentate, or entire.

(petiole slightly winged);

blade oblanceolate, elliptic, or rhombic, (mostly flat, sometimes somewhat folded), 0.6–2.7 cm, (base tapering to petiole), margins entire, (apex rounded to rounded-acute).

(proximal sometimes petiolate, distal sessile);

blade linear to oblanceolate, often falcate, 1–4(–7) cm, (proximal with base sometimes cuneate), margins entire, repand, or shallowly dentate.

dense.

crowded, (ca. 3–7 fruits).
