few to many, decumbent-based to erect, unbranched except for short, leafy axillary shoots, hairs sparse, spreading, medium length to long, soft and dense, short to medium length, stipitate-glandular.

few to several, ascending to erect, unbranched, hairs moderately dense, often retrorse, short, ± stiff, stipitate-glandular distally only in inflorescence.

green or gray-green to purple (sometimes different on stems of same plant), linear-lanceolate, distal sometimes broadly lanceolate, 0.5–4 cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex acute to acuminate;

lobes ascending, linear to narrowly lanceolate, apex acute to acuminate, rarely obtuse.

appressed-ascending, green to purplish, linear to narrowly lanceolate, distal sometimes broadly lanceolate, (1–)2.5–4(–5.5) cm, not fleshy, margins plane, involute, 0(–5)-lobed, apex rounded to acuminate;
