several from base, decumbent to prostrate, (well-exserted beyond basal leaves), 0.2–0.5 dm.

blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate.

(petiole differentiated from blade);

blade (slightly cupped, leathery, nearly 1 mm thick), oblanceolate to orbicular, 1.2–2 cm, margins entire, (apex acute).

blade usually linear to narrowly oblanceolate, rarely elliptic to rhombic, 0.5–2.5 cm, (base narrowing to petiole), margins entire or remotely dentate (sometimes involute).

blade spatulate, similar to basal.

loose to somewhat dense.

dense, (subumbellate).

sepals elliptic to oblong, 5–8 mm, (lateral pair not saccate, median pair often thickened apically, ± cucullate);
