petiole 1–3 cm;

blade oblanceolate, 1–3 × 0.4–0.8 cm, thinly pubescent.

rather dense with secondary branches suppressed, grayish;

bracts 2, similar to leaf blades at proximal nodes only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 0.5–7 cm × 2–7 mm, awns 0.5–1.2 mm.

with involucres in dense clusters 2–4 cm diam., greenish or reddish to purple;

bracts 2–3 at proximal node, usually leaflike, often with whorl of sessile bracts about midstem, elliptic, 0.5–1.5 cm × 2–6 mm, becoming gradually lanceolate to elliptic, 0.2–1 cm × 1.5–5 mm, at distal nodes scalelike, linear and aciculate, acerose, awns straight, 1–3 mm.
