Treatment appears in FNA Volume 20. Treatment on page 567. Mentioned on page 545.

Annuals, 20–40 (–60) cm (taprooted). Herbage (somewhat sticky) hairy or unevenly glabrate. Stems single (often branching distally). Leaves evenly distributed; petiolate (petiole bases ± expanded); blades obovate (lyrate to pinnatifid, lobes linear to ± cruciate), 3–8 × 1.5–3.5 cm, bases contracted or tapered, ultimate margins ± dentate to crenate. Heads 8–20 in corymbiform arrays. Calyculi of 8–14 ± ovate bractlets (lengths to 1/2 phyllaries). Phyllaries ± 13+, 6–10 mm, tips black. Ray-florets ± 13; corolla laminae (deep red to purple) 10–15 mm. Cypselae usually hairy. 2n = 20.


Phenology: Flowering mostly spring–summer (sparingly at other times).
Habitat: Disturbed coastal sites
Elevation: 0–100 m

Distribution

Introduced; Calif., Africa

Discussion
