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

simple or few from base, decumbent, (straggling and flexuous, usually branched distally), 4–8 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 narrowly elliptic to oblanceolate, 4–12 cm, margins entire, sinuate, or shallowly dentate, (apex acute).

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

(sessile or proximal shortly petiolate);

blade linear to narrowly elliptic, 3–4 cm, margins entire, sinuate, or remotely dentate, (apex acute).

moderately dense (or elongated).

loose, (sometimes greatly elongated).

sepals linear-oblong, 6–8 mm;

petals spatulate, 9–12 mm.

sepals elliptic, 3.5–4 mm, (lateral pair subsaccate, median pair thickened apically, cucullate);
