many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

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 or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute to 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;
