Herbs, matted, scapose, 0.2–1.5 × 0.5–4 dm, tomentose or floccose to subglabrous, greenish or grayish. Stems matted, with persistent leaf-bases, up to 1/5 height of plant; caudex stems matted; aerial flowering-stems scapelike, erect, slender, solid, not fistulose, 0.2–1 (–1.5) dm, tomentose or floccose to subglabrous or even glabrous. Leaves basal, fasciculate in terminal tufts; petiole (0.2–) 0.4–2 (–3) cm, tomentose; blade oblanceolate to spatulate or elliptic, 0.5–1.5 (–2) × (0.2–) 0.3–0.8 (–1) cm, densely white or greenish-tomentose on both surfaces, margins plane. Inflorescences capitate, 0.8–1.7 (–2) cm; branches absent; bracts 3–5, linear to narrowly scalelike, triangular, 1.5–3 mm. Peduncles absent. Involucres 3–5 per cluster, turbinate-campanulate to campanulate, 2.5–3.5 × 2.5–4 mm, membranous, sparsely pubescent or rarely sparsely glandular abaxially; teeth 5–6, erect to spreading, 0.7–1.8 (–2) mm. Flowers (2.5–) 3–3.5 mm; perianth greenish yellow or pale-yellow, rarely yellow, glabrous or sparsely glandular abaxially; tepals connate proximal 1/4–1/2, monomorphic, spatulate to obovate; stamens exserted, 2–3.5 mm; filaments glabrous or sparsely pilose proximally. Achenes light-brown, 2.5–3 mm, glabrous except for slightly papillate beak in some. 2n = 40.


Phenology: Flowering Jun–Sep.
