few to many, erect, ± decumbent or creeping at base, unbranched, sometimes branched, hairs spreading, medium length and long, soft, mixed with short stipitate-glandular ones.

several, decumbent, often sprawling, distally ascending, unbranched unless injured, rarely with small, leafy axillary shoots, hairs spreading, whitish, short, ± stiff, eglandular.

green to purple or brown-tinged, linear-lanceolate proximally, oblong-ovate or -obovate distally, 0.8–5.2 cm, not fleshy, margins plane, distalmost sometimes ± wavy, involute, 3–7(–11)-lobed, apex obtuse;

lobes erect to ascending, linear to linear-spatulate, very short, toothlike, usually arising from distal 1/3 of blade, apex rounded.

gray-green, sometimes green or reddish purple, reduced and scalelike on proximal 10–25% of stem, linear, lanceolate, or narrowly elliptic, 1.5–4(–5) cm, not fleshy, margins plane, flat or involute, 0–3(–5)-lobed, apex acute;
