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(–6) cm;

blade oblanceolate, 0.5–2(–4) × 0.1–0.4(–1) cm, villous.

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.

cymose, dichotomously branched throughout, white to greenish or reddish;

bracts usually 2, similar to proximal leaf blades, typically with whorl of 3–5 ca. midstem, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 0.5–2(–3) cm × 1–5(–10) mm, awns absent.

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.

congested in small leafy terminal clusters of 2–4 at nodes of dichotomies, greenish, cylindric, slightly ventricose basally, 3–5 mm, with conspicuous, purple, broad, membranous margins typically extending across sinuses, finely corrugated, hispid at least along ridges, otherwise sparsely pubescent;

teeth spreading, equal, (0.7–)1–1.5 mm, awns straight, 0.5–1 mm.

long-exserted;

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

tepals connate ca. 1/2 their length, dimorphic or sometimes monomorphic, narrowly oblanceolate, apex rounded, those of outer whorl slightly broader and occasionally longer than those of inner whorl;

stamens 9, mostly included;

filaments distinct, 4–6 mm, glabrous;

anthers pink to red, ovate to oblong, 0.5–0.6 mm.

exserted;

perianth white to rose, cylindric, 3.5–4(–4.5) mm, slightly pubescent abaxially;

tepals connate 2/3 their length, monomorphic, obovate, 2-lobed or denticulate apically, infrequently inner whorl entire;

stamens 9, slightly exserted;

filaments distinct, 3–4 mm, glabrous;

anthers pink to red, oblong, 0.5–0.6 mm.

brown, lenticular, 3–4 mm.

light brown, globose-lenticular, 3.5–4 mm.
