Biennials or short-lived perennials (sometimes appearing annual), 2–45 (–60) cm; fibrous-rooted, caudices simple. Stems erect or basally ascending, sparsely to densely hirsute, eglandular.

Heads 1 or 3–12 usually in loosely racemiform arrays (from erect peduncles distal to midstems, sometimes on proximal 1/3). Involucres 4–9 × 7–17 mm. Phyllaries in 2–3 series (inner apices acute to acuminate), hirsute to strigoso-hirsute, eglandular. Ray (pistillate) florets 70–130 (in 1 series); corollas white to light pink, 2–3 mm, laminae (filiform) erect, not coiling or reflexing (not surpassing involucres). Disc corollas 3–5 mm. Cypselae 1.3–1.8 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 20–30 (non accrescent) bristles. 2n = 18.
