Plants 10–50 cm (relatively slender); self-compatible. Stems (often purplish, especially distally, slender, usually less than 3 mm diam. at bases) branched (branches often relatively many, usually from near midstems, arcuate to ascend-ing), glabrous. Leaves mostly alternate, 2–5 cm (proximal), hispidulous and ± long-hairy (especially margins and adaxial faces). Heads borne singly or in ± spiciform arrays (1–3 per node, ± sessile). Peduncular bracts lance-oblong to linear, 2–4 mm (nearly terete to strongly flattened, glabrous or hispid overall, sometimes pectinate-fimbriate), apices ± rounded, tack-glands usually 1 (terminal). Phyllaries 4–5 mm, abaxial faces glabrous or ± hispid distally or sparsely bristly, shaggy long-hairy on margins distally, tack glands 0(–1) (terminal). Paleae 5–6 mm. Ray florets 1–3(–6); corollas bright yellow, tubes 1–1.5 mm, laminae 2–2.5(–3) mm (central lobes smaller than laterals, oblong to narrowly triangular, symmetric, widest at bases, laterals asymmetric, sinuses 1/4 laminae). Disc florets 1–3; corollas yellowish, 3–4 mm. Ray cypselae ca. 3 mm, rough-wrinkled, glabrous. Disc cypselae ca. 3 mm (seldom formed, terete and tapered toward bases, smooth to ± ridged, glabrous); pappi 0. 2n = 14.
