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.

few to several, erect or ascending, sometimes decumbent at base, unbranched or branched, hairs usually retrorse, medium length, ± soft, eglandular, mixed with very short-glandular ones, sometimes with spreading, long, soft ones.

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.

green to purple, linear to lanceolate, 2–7 cm, not fleshy, margins plane, involute, 3–5(–7)-lobed, apex acuminate to acute;
