basal or nearly so;

petiole 1–4(–7) cm;

blade oblanceolate, 1.5–5 × 0.2–0.7(–1) cm, villous.

basal;

petiole 0.5–2 cm;

blade (0.3–)0.5–1.5(–2) × (3–)5–10(–12) mm, thinly pubescent adaxially, more densely so to tomentose abaxially.

with secondary branches not suppressed except in terminal clusters of involucres, green to reddish;

bracts 2, similar to proximal leaf blades only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 1–5 cm × 2–5(–7) mm, awns absent.

greenish to reddish, mostly flat-topped and open to dense;

bracts 3, whorled, short-petiolate, linear-lanceolate to lanceolate, acerose, 0.5–1.5 cm × 3–8(–10) mm, awns straight, 1–3.5 mm.

1, greenish, cylindric, not ventricose, 2.5–4 mm, with white to pinkish, thin scarious margins restricted to basal portion of teeth, not corrugate, thinly pubescent abaxially;

teeth spreading, equal, 0.3–0.8(–1) mm;

awns uncinate with longer ones 0.7–1.3 mm and anterior one mostly 1–1.3 mm, these alternating with shorter (0.3–0.7 mm) ones.

usually congested in small terminal clusters of 1–3 at node of dichotomies, (4–)5-ribbed, weakly 3-angled, 2–2.5 mm, not corrugate, densely canescent;

teeth (4–)5, essentially erect with longer, prominent, and thickened anterior one 2–4 mm, with straight awn 1–2.5 mm, remaining teeth smaller, 0.5–1 mm, with straight awns 0.3–0.8 mm.

slightly exserted;

perianth bicolored with floral tube white and tepals white to rose, cylindric, 2.5–4 mm, pubescent abaxially;

tepals connate 1/4 their length, monomorphic, oblanceolate to narrowly oblong, usually truncate to rounded and erose or denticulate apically, occasionally distinctly cuspidate;

stamens 9, included;

filaments distinct, 2–3.5 mm, glabrous;

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

perianth, cylindric, 2.5–3.5 mm;

tepals connate 1/2–2/3 their length, dimorphic, entire, those of outer whorl spreading, broadly obovate and rounded apically, those of inner whorl erect, narrowly oblanceolate, 1/2 length of outer ones, acute apically;

stamens slightly exserted;

filaments 2.5–3 mm, glabrous;

anthers yellowish, oblong, 0.5–0.7 mm.

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

2.5–3 mm.
