Stems mostly erect, without persistent leaf bases, up to 1/2 height or more of plant; caudex stems absent; aerial flowering stems erect, stout, solid, not fistulose, 2–4 dm, tomentose. Leaves 1 per node and sheathing up stems or fasciculate at tips of basal branches; petiole 0.1–0.5(–1) cm, tomentose; blade oblanceolate to narrowly oblong, (1.5–)2–4(–5) × 1–2.5(–3) cm, densely white-tomentose abaxially, floccose adaxially, margins plane. Inflorescences cymose, 15–30(–40) × 15–40 cm; branches dichotomous, tomentose; bracts 3, semileaflike, narrowly oblanceolate, 3–7 × 1–3 mm. Peduncles absent or erect, slender, (1–)3–10 cm, tomentose. Involucres 1 per node, turbinate-campanulate, 3.5–5 × 2.5–4 mm, tomentose; teeth 5–8, erect, 0.4–0.8 mm. Flowers 3–6(–7) mm; perianth white, densely villous abaxially; tepals connate proximal 1/3, monomorphic, narrowly oblong; stamens exserted, 3–7 mm; filaments pilose proximally.
