several from base, decumbent to ascending (arising laterally, unbranched, stout), (0.2–)0.5–1.7 dm.

several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm.

(petiole somewhat winged);

blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy).

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

blade oblanceolate to broadly spatulate, 1–2 cm (width 3–5 mm), margins entire, (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).

moderately dense (or elongated).

loose to somewhat dense.

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

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