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.

rather dense with secondary branches suppressed, white to greenish;

bracts 2, similar to leaf blades at proximal nodes only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 0.3–2 cm × 1–4 mm, awns absent.

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.

1, mostly greenish, cylindric, not ventricose, 2–2.5 mm, with thin to broad and then conspicuous white or pinkish to purple, scarious margins extending nearly full length of awn, not corrugate, villous-hirsute;

teeth spreading to divergent, equal, 0.5–1 mm, awns uncinate with longer ones 1–2 mm, anterior one mostly 2 mm, alternating with shorter (0.5–1 mm) ones.

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.

exserted;

perianth bicolored with floral tube lemon-yellow and tepals white, campanulate, 2.5–3 mm, glabrous;

tepals connate ca. 1/3 their length, monomorphic, oblong, acute to obtuse and entire apically;

stamens 3–9, slightly exserted;

filaments distinct, 1.5–2 mm, glabrous;

anthers yellow, oval, 0.3–0.4 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.
