several from base, erect to decumbent or prostrate, (unbranched or branched, sometimes densely leaved), 1–3.5(–4.5) dm.

several (to several hundred) from base, erect, (each terminating in a tufted cluster of leaves), to 7 dm.

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

(petiole not differentiated from blade);

blade narrowly elliptic to narrowly linear-oblanceolate, (0.8–)1–1.5 cm, (base cuneate), margins entire.

(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.

similar to basal, blade sometimes linear, (apex acute).

dense.

dense, (often ± subumbellate, somewhat elongated in fruit).

sepals elliptic or oblong, 3–6.5 mm, (lateral pair subsaccate, median pair thickened apically, cucullate);

(divaricate-ascending, sigmoid or, sometimes, nearly straight), 5–15(–25) mm.

(strongly sigmoid), 5–10 mm.

(shortly stipitate), subglobose, not or slightly compressed, (3–)4–8 mm;
