Herbs, erect to slightly spreading, 0.5-3(-5) dm, thinly tomentose to floccose or glabrous, grayish or reddish gray. Stems: aerial flowering stems erect, 0.5-1 dm, thinly tomentose to floccose, infrequently glabrous, straight or nearly so, infrequently inwardly curved distally. Leaves basal; petiole 1-4 cm, mostly floccose; blade round-ovate to rounded, 0.5-2(-2.5) × 0.5-2 cm, white-tomentose abaxially, less so to nearly glabrous and grayish or greenish adaxially. Inflorescences cymose, often distally uniparous due to suppression of secondary branches, open to somewhat diffuse, 5-25 × 5-25 cm; branches floccose or glabrous; bracts 1-3 × 1-2 mm. Peduncles absent. Involucres appressed to branches, narrowly cylindric, 2-3.5(-4) × 1-2 mm, glabrous or infrequently floccose; teeth 5, erect, 0.3-0.6 mm. Flowers 2-2.5 mm; perianth white to rose or pale yellow, glabrous; tepals slightly dimorphic, those of outer whorl broadly spatulate to obovate, those of inner whorl oblanceolate; stamens included, 1-1.5 mm; filaments pilose proximally or glabrous. Achenes brown, 3-gonous, 2-2.5 mm. 2n = 24.
