basal or nearly so;

petiole 1–4 cm;

blade spatulate to broadly obovate, 1–3 × 0.5–1.5(–1.8) cm, villous.

basal;

petiole 0.5–3 cm;

blade elliptic to oblong, 0.5–2 × 0.2–0.6 cm, thinly pubescent adaxially, tomentose abaxially.

with secondary branches suppressed, greenish to grayish;

bracts 2, similar to proximal leaf blades only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 1–5 cm × 5–15 mm, awns absent.

mostly flat-topped, openly branched, greenish to reddish;

bracts persistent, 2, usually leaflike at proximal nodes and similar to leaf blades, short-petiolate, oblong, 0.5–1.2 cm × 2–4 mm, 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.

1, greenish to grayish, broadly cylindric, not ventricose, 3–4 mm, with conspicuous, white, scarious margins between teeth and extending up awn, not corrugate, pubescent;

teeth spreading, equal, 0.5–1 mm, awns straight with longer ones 1–2 mm and anterior one mostly 2 mm, these alternating with shorter (0.5–1 mm) ones.

in dense terminal clusters with 1 at node of dichotomies, reddish, cylindric, not ventricose, 2–2.5 mm, corrugate, without scarious or membranous margins, thinly pubescent with stoutish, recurved hairs;

teeth spreading, unequal, 0.3–0.8(–1) mm, with 3 longer ones more erect than 3 shorter and less-prominent ones;

awns uncinate, 0.3–0.5 mm.

exserted;

perianth bicolored with floral tube white and tepals white to rose, cylindric, (3–)3.5–4.5 mm, pubescent nearly throughout;

tepals connate 1/4 their length, dimorphic, oblong, truncate and erose to denticulate apically, those of outer lobes longer and wider than inner ones;

stamens 9, included;

filaments distinct, 3–4 mm, glabrous;

anthers pink to red, oblong, 0.6–0.8 mm.
