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, erect or ascending, branched or unbranched, sometimes with axillary tufts of leaves, hairs spreading to ± appressed, ± matted, short, soft, 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;
