basal or nearly so;

petiole 1–4 cm;

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

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

bracts usually 2, similar to leaves at proximal nodes only reduced, typically with whorl of 3–5 ca. midstem, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 0.5–2(–3) cm × 10–30(–40) mm, awns absent.

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.

congested in small bracteated terminal clusters of 2–4 at node of dichotomies, tannish, cylindric, slightly ventricose basally, 3–4 mm, with conspicuous, white, broad, membranous margins typically extending up tooth to awn, finely corrugated, hispid at least along ridges, otherwise sparsely pubescent;

teeth spreading, equal, 1–1.5 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.

exserted;

perianth cream to creamy white or rose, cylindric, 4–4.5(–5) mm, slightly pubescent abaxially;

tepals connate 2/3 their length, monomorphic, obovate, obcordate to 2-lobed apically, sometimes slightly irregular but not distinctly erose;

stamens 9, slightly exserted;

filaments distinct, 4–5 mm, glabrous;

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

exserted;

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