few to many, decumbent to ascending, much-branched, with leafy axillary shoots, villous, hairs spreading, long, stiff to soft, eglandular, mixed with short-glandular ones.

green to purple-tinged, linear to linear-lanceolate, (1–)2–8 cm, not fleshy, margins plane, flat, 0(–5)-lobed, apex acuminate;

lobes spreading to ascending, filiform to lanceolate, apex sometimes acuminate.

gray-green becoming ± purple, or green, ± cup-shaped, oblong to narrowly elliptic or suborbicular, 0.5–2(–5) cm, ± fleshy, cupulate throughout, sometimes obscurely so on distal portion of stem, margins plane, flat to involute, 0–3-lobed, apex rounded;

lobes ascending, oblong to rounded, apex truncate or rounded, sometimes ± acute.
