several from base, erect to decumbent, (unbranched, stout, densely leafy sterile shoots sometimes present), (0.5–)4–2.5 dm.

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

(clustered at stem base);

blade linear to linear-oblanceolate, 2–5 cm, margins entire, usually involute, sometimes flattened, (apex obtuse to subacute).

(shortly petiolate);

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).

loose to somewhat dense.

compact, (often nearly subumbellate).

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

petals (usually orange or orange-yellow at junction of blade and claw, sometimes also with orange guidelines), obdeltate to obovate, 8–12 mm, (claw relatively short).
