blade oblanceolate, 0.5–1.5(–2) × 0.2–0.8 cm, thinly pubescent.

mostly flat-topped and openly branched, usually reddish;

bracts persistent, 2, usually leaflike at proximal nodes and similar to proximal leaf blades only more reduced, short-petiolate, oblong-ovate to ovate, 0.3–0.8 cm × 2–6 mm, becoming sessile, reduced and scalelike at distal nodes, linear, acicular, often acerose, 0.1–0.4 cm × 0.5–1 mm, awns straight, 0.5–1 mm.

with involucres in small open clusters 0.5–1.5 cm diam., greenish to grayish or reddish;

bracts 2, sessile, usually leaflike, oblanceolate to elliptic, 0.5–1.5 cm × 1.5–5 mm, gradually reduced and becoming scalelike at distal nodes, linear, aciculate, acerose, 0.4–1.2 cm × 1–2(–3) mm, awns straight, 1.5–4 mm.

in open clusters with 1 at node of dichotomies, reddish, cylindric, not ventricose, 3–4.5 mm, not corrugate, without scarious or membranous margins, thinly to densely pubescent;

teeth spreading, unequal, 0.7–1.5 mm, 3 longer ones more erect than 3 shorter and less-prominent ones;

awns uncinate, 0.5–1 mm.

3–10, grayish to reddish, urceolate, slightly ventricose basally, 2–3 mm, without scarious or membranous margins, slightly corrugate, densely grayish-pubescent;

teeth widely spreading to divergent, unequal, 0.3–0.5 or 3–6 mm;

awns straight or uncinate, unequal, with longer anterior one straight, 2.5–5.5 mm, others spreading, uncinate, 0.3–0.5 mm.

long-exserted;

perianth rose to red, infrequently with white lobes, cylindric, 4.5–6 mm, pubescent;

tepals connate ca. 2/3 their length, monomorphic to slightly dimorphic, narrowly oblanceolate, rounded apically, those of outer whorl occasionally slightly broader and longer than those of inner whorl;

filaments distinct, 1–2 mm, glabrous;

anthers white, ovate, 0.4–0.5 mm.
