Characteristics

Plants 10–50 cm; self-incom-patible. Stems branched (plants without obvious main axes, branches usually relatively many, slender, usually divergent, often zigzag), finely strigose (some hairs longer). Leaves mostly alternate, 1–5 cm (proximal), ± hispidulous and ± long-hairy (proximal margins and adaxial faces). Heads borne singly or in open, spiciform arrays (1–4 per node). Peduncular bracts ± linear to narrowly elliptic to oblanceolate, 2–3 mm (hispidulous, ± bristly and/or pectinate-fimbriate), apices rounded to truncate, tack-glands 1–3+. Phyllaries 4–6 mm, abaxial faces scabrous, ± strongly bristly, ± shaggy long-hairy on distal margins, tack-glands (0–)1–7+. Paleae 4–6 mm (receptacular cups ± clavate to fusiform, lengths ± 2 times diams.). Ray florets 1(–2); corollas white to reddish, tubes ca. 2 mm (papillate), laminae 5–7 mm (central lobes equaling or slightly narrower than laterals, ± elliptic or distally broader and more rounded, symmetric or nearly so, widest near or beyond middles, sinuses nearly equaling laminae). Disc florets 2–5; corollas white to pinkish, ca. 5–6 mm. Ray cypselae 2.5–4 mm, smooth, usually glabrous, sometimes hairy distally, sometimes with slightly elevated areolae. Disc cypselae angular, 2.5–3.5 mm, appressed hairy, especially on angles; pappi of ca. 8–10 lanceolate-attenuate and shorter, blunt fimbriate scales ca. 1–2.5 mm (alternating). 2n = 10, 12.
