with secondary branches not suppressed except in terminal clusters of involucres, green to reddish;

bracts 2, similar to proximal leaf blades only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 1–5 cm × 2–5(–7) mm, awns absent.

with involucres in open clusters 2–6 cm diam., greenish or reddish;

bracts 2–3 at proximal node, usually leaflike, often with whorl of sessile bracts about midstem, oblanceolate to elliptic, 0.5–1.5 cm × 1–4 mm, gradually becoming reduced, linear-lanceolate, 0.4–1.2(–1.5) cm × 1.5–5 mm, at distal nodes scalelike, linear and aciculate, acerose, awns straight, 1–3 mm.

teeth spreading, equal, 0.3–0.8(–1) mm;

awns uncinate with longer ones 0.7–1.3 mm and anterior one mostly 1–1.3 mm, these alternating with shorter (0.3–0.7 mm) ones.
