Information Annuals or short-lived perennials, (7–)12–40(–70) cm; taprooted, caudices simple if perennial. Stems (single or multiple from bases) erect to ascending, densely and evenly puberulous-hirsutulous (hairs spreading to spreading-descending or -ascending, often crinkly, bases not thickened), minutely glandular at least distally, usually throughout. Leaves basal (usually deciduous) and cauline; basal blades obovate-spatulate, 10–70 × 4–-14 mm, cauline gradually reduced distally, margins entire or with 2–3 pairs of teeth or lobes, faces hirsute to loosely strigoso-hirsute, sometimes sparsely glandular. Heads (in early season, 1–)5–100+ (buds nodding). Involucres 3–4 × (5–)7–11 mm. Phyllaries in 3–4 series, hirsute, minutely glandular. Ray florets 75–150; corollas white, drying lilac, without abaxial midstripe, (2–)4–9.5 mm, laminae not coiling or reflexing (remaining relatively straight). Disc corollas 1.8–2.3 mm (throats indurate and slightly inflated). Cypselae 0.9–1.2 mm, 2-nerved (nerves whitish), faces sparsely strigose; pappi: outer of setae or scales, inner of 6–9(–12) bristles. 2n = 18, 27, 36.

Information Plants spreading, 5–25+ cm, branched throughout (stems usually ± strigose). Leaves: faces closely strigose; proximal blades narrowly spatulate to linear, 5–15+ × 0.5–2(–3+) mm; distal similar, smaller, narrower. Heads in loose, corymbiform arrays or borne ± singly. Involucres 3–4 mm. Phyllaries glabrous or glabrate; outer greenish to purplish, lanceolate, shorter, sparsely strigose; inner stramineous to purplish, linear-attenuate (more scarious). Receptacles 0.7–1 mm diam. in fruit. Pistillate florets 20–30; corollas ± equaling or surpassing styles, laminae 0.3–0.8 mm. Disc florets 3–8. Cypselae pale tan, 1–1.5 mm, faces sparsely strigillose or glabrous; pappi of 20–30, tawny to pinkish bristles 2–2.5 mm. 2n = 18.
