Shrubs, erect to spreading, not scapose, (2-)3-10(-12) × 5-15(-20) dm, white-tomentose to floccose, or green and nearly glabrous. Stems spreading, often without persistent leaf bases, up to 2 height of plant; caudex stems absent or spreading in moving sand; aerial flowering stems spreading, slender, solid, not fistulose, 0.3-1 dm, white-tomentose, floccose to glabrate or glabrous. Leaves cauline, 1 per node; petiole 0.2-0.5 cm, tomentose to floccose; blade linear-lanceolate to linear-oblanceolate to narrowly oblong, or lanceolate to narrowly elliptic, 1.5-4 × 0.2-0.8(-1.2) cm, densely white-tomentose abaxially, less so and greenish adaxially, margins plane, infrequently revolute. Inflorescences cymose, open, 5-40 × 10-50 cm; branches dichtomous proximally, often with involucres racemosely arranged proximally, tomentose to floccose or glabrate, occasionally glabrous; bracts 3, scalelike, linear to triangular, 1-3(-6) mm. Peduncles absent. Involucres 1 per node, turbinate to turbinate-campanulate, 1.5-3 × 1-2 mm, tomentose to floccose or glabrous; teeth 5, erect, 0.4-0.7 mm. Flowers (2-)2.5-3.5 mm; perianth white or pale yellow to yellow, glabrous; tepals connate proximal 1/ 1/ 3, essentially monomorphic, oblong to broadly obovate; stamens slightly exserted, 2-4 mm; filaments sparsely pilose proximally. Achenes light brown, 2.5-3.5 mm, glabrous except for minutely papillate beak.
