basal;

petiole 1–3(–4) cm;

blade oblong to oblong-ovate, 0.5–2(–3) × 0.3–0.5(–0.7) cm, thinly pubescent adaxially, usually densely tomentose adaxially.

basal;

petiole 1–3 cm;

blade spatulate to ovate, 0.5–2 × 0.3–1.2(–1.5) cm, thinly pubescent to densely tomentose at least abaxially.

mostly flat-topped and openly branched, usually reddish;

bracts soon deciduous, 2, occasionally leaflike at proximal nodes and similar to proximal leaf blades only more reduced, short-petiolate, ovate, 0.3–0.4 cm × 2–3 mm, otherwise sessile, linear and acicular, often acerose, 0.1–0.3 cm × 0.7–1 mm, awns straight, 0.5–1 mm.

mostly flat-topped, open to rather densely branched, greenish to reddish;

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

in congested clusters with 1 at node of dichotomies, reddish, cylindric, not ventricose, 3–4 mm, not corrugate, without scarious or membranous margins, thinly pubescent;

teeth spreading, unequal, 0.7–1.5 mm with longer of 3 longest ones more erect than 3 other shorter and less-prominent ones, awns uncinate, 0.5–1 mm.

in open clusters with 1 at node of dichotomies, reddish, cylindric, not ventricose, 2.5–3 mm, corrugate, without scarious or membranous margins, thinly pubescent with slender curly hairs;
