few to many, erect or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly.

solitary, erect, unbranched or branched, hairs spreading, medium length and long, soft to ± stiff, mixed with shorter stipitate-glandular ones.

green, linear to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;

lobes divergent, spreading-ascending, linear, apex acute to acuminate.

green to purple, linear to narrowly lanceolate, 0.5–4.2 cm, not fleshy, margins plane, flat, 0(–5)-lobed, apex acuminate to acute;

lobes ascending to erect, linear to narrowly lanceolate, apex acuminate.

5–22 × 1–4.5 cm;

bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;

lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones acute.

1.5–15 × 1.5–3 cm;

bracts green throughout, or proximally green, distally white to rarely cream on apices, with a tuft of erect, white, soft hairs, especially when immature, narrowly lanceolate to narrowly ovate, 3–5-lobed;
