solitary or few, erect, unbranched or branched, hairs spreading, short to long, ± stiff, mixed with short stipitate-glandular ones.

solitary or few, erect to erect-ascending, sometimes slightly curved at base, branched at base or unbranched, hairs spreading, long, stiff to soft, mixed with shorter stipitate-glandular ones.

green, linear to narrowly lanceolate or narrowly oblong, 2–5.7 cm, not fleshy, margins plane, flat, 3–7(–9)-lobed, apex acuminate to acute;
