Subshrubs, 10–60(–100) cm. Stems minutely hispidulous. Leaves: basal and proximal absent at flowering; cauline blades 1-or 3-nerved, linear to lanceolate, sometimes filiform and fascicled, 1.5–2(–3) mm wide, little reduced distally. Heads (sessile to subsessile in compact glomerules) in dense, flat-topped, corymbiform arrays. Involucres cylindric to cuneate-campanulate, 1.5–2(–3) mm diam. Phyllary apices flat. Ray florets (2–)3–8; corollas yellow, 3–5.5 mm. Disc florets (2–)3–9 (usually bisexual and fertile, rarely functionally staminate, corollas tubular-funnelform, lobes erect to spreading or recurved, deltate). Cypselae 0.8–1.6(–2.2) mm, faces without oil cavities, densely strigoso-sericeous; pappi of 1–2 series of narrowly oblong-to ovate-lanceolate or obovate scales (readily falling, those of discs 1 / 3 – 1 / 2 corollas, shorter on rays). 2n = 8, 16, 32.

Dry soils of open areas, plains, valleys and foothills. Open or disturbed sites in Texas, often on calcareous soils. Often abundant on overgrazed pastures.
