Herbs, erect or matted, sometimes scapose, 1–3.5 × 1–2 dm or 0.05–0.2 × 0.5–3.5 dm, floccose or silky-tomentose, grayish. Stems spreading or matted, occasionally with persistent leaf bases, up to 1/4 or more height of plant; caudex stems matted; aerial flowering stems erect or nearly so, slender, solid, not fistulose, 1–2 dm and floccose, or (0.1–)0.02–0.5(–0.65) dm and silky-tomentose.
