Annuals, 30–70 (–90+) cm. Cauline leaves ± scattered over proximal 1/4–1/2 (–3/4) of plant heights, internodes mostly 4–10 cm; lobes mostly linear to filiform, sometimes ± oblong, 25–50 (–120) × 0.5–1+ mm. Calyculi of 6–7+ narrowly triangular bractlets 2–4 mm. Ray-florets 8; laminae yellow to golden, usually proximally, sometimes almost wholly, suffused with redbrown or with a redbrown spot or band, 10–20+ mm. Disc corollas redbrown, throats shorter than lobes. Cypselae 5–5.5+ mm; pappi 0.5–1+ mm. 2n = 20.
Phenology: Flowering Mar–Jul.
Habitat: Disturbed sites on sands
