Shrubs, spreading or rarely sprawling, not scapose, (1.5-)3-8(-10) × 3-12(-15) dm, tomentose or rarely floccose to glabrate, grayish. Stems decumbent to spreading, often without persistent leaf bases, up to 1/ 3 height or more of plant; caudex stems absent or spreading in moving sand; aerial flowering stems spreading, slender to stout, solid, not fistulose, 0.5-1 dm, tomentose to floccose. Leaves cauline, 1 per node; petiole 0.2-1 cm, tomentose to floccose; blade broadly oblanceolate to elliptic or, rarely, orbiculate, (0.5-)1-3 × 0.4-1.2(-1.5) cm, densely white-tomentose abaxially, less so and greenish adaxially, margins plane. Inflorescences cymose, open, 5-50 × 5-80 cm; branches dichotomous proximally, often with involucres racemosely arranged distally, tomentose to thinly floccose, rarely glabrate; bracts 3, scalelike, linear to triangular, 0.5-6 mm. Peduncles absent or erect, 0.5-3 cm, tomentose. Involucres 1 per node, turbinate to turbinate-campanulate, 2-3 × 1.5-2.7 mm, tomentose or nearly so; teeth 5, erect, 0.1-0.4 mm. Flowers 1.5-3 mm; perianth white, glabrous; tepals connate proximal 1/ 4, essentially monomorphic, obovate; stamens slightly to long-exserted, 2-5 mm; filaments subglabrous or sparsely puberulent proximally. Achenes light brown, 2-3 mm, glabrous. 2n = 80.
