Plants 10–100 cm; self-incom-patible. Stems simple or branched (main axes usually obvious, branches relatively few, ± rigid), hispidulous to strigose (especially proximally, usually strigose with scattered, stouter hairs distally). Leaves mostly alternate, 2–8 cm (proximal), hispid to hispidulous and ± long-hairy (especially on margins and adaxial faces). Heads borne singly or in open, spiciform arrays (1–2+ per node). Peduncular bracts narrowly elliptic to oblanceolate, 2–10 mm (hispidulous, ± bristly and/or strongly pectinate-fimbriate) apices rounded or truncate, tack-glands 1–5+. Phyllaries 3–7 mm, abaxial faces ± hispidulous, ± bristly, shaggy long-hairy on distal margins, tack-glands (0–)1–5+. Paleae 3–7 mm (receptacular cups ± campanulate, lengths often ± equaling diams.). Ray florets (1–)2–6; corollas white or cream to pinkish, or yellow (sometimes basally reddish), tubes 1–2 mm (± papillate, throats sometimes with dark red "eyes"), laminae 4.5–7 mm (central lobes ± equaling or narrower than laterals, mostly obovate, widest beyond middles, sinuses nearly equaling laminae). Disc florets (4–)6–21; corollas white to pinkish, or yellow, 4–5 mm. Ray cypselae 2.5–4 mm, smooth, glabrous or glabrate. Disc cypselae 2–4 mm (often ± angular), appressed-hairy; pappi of 8–14 long-aristate and short-blunt, fimbriate scales 1–3 mm (alternating). 2n = 12.
