Found in FNA Volume 21. Treatment on page 245. Mentioned on page 5, 253.
Annuals, perennials, or subshrubs, 10–80 cm (often ± succulent). Leaves cauline; opposite; petiolate or sessile; blades (1- or 3-nerved) oblong, oblong-ovate, lanceolate, linear, or filiform, margins entire or toothed, faces glabrous, glabrescent, or puberulent. Heads radiate or discoid, in glomerules or corymbiform to paniculiform arrays. Calyculi 0 or of 1–2 bractlets. Involucres campanulate, cylindric, obconic, turbinate, or urceolate. Phyllaries persistent, 2–8 in ± 1 series (distinct, linear to oblong, subequal, ± succulent to membranous or scarious). Receptacles flat to convex, epaleate. Ray florets 0, or 1–6, pistillate, fertile; corollas yellow. Disc florets 1–60[–100+], bisexual, fertile; corollas yellow, tubes shorter than or about equaling the funnelform to campanulate throats, lobes 5, deltate; anther thecae pale; stigmatic papillae in 2 lines. Cypselae cylindric to clavate or ± compresssed, linear-oblong to oblanceolate, 10–15-ribbed, glabrous or hairy; pappi 0, or persistent, coroniform, or of 2–5 ovate, scarious scales, or of 20–25+ unequal bristles, or of 5 scales plus 5 bristles (all in 1 series, sometimes connate).

Distribution

Mostly subtropical, tropical, and warm-temperate New World.

Discussion

Genera 3, species 27 (3 genera, 10 species in the flora).

As noted by H. Robinson (1981), traditionally, Flaveria and Sartwellia were treated in Helenieae, Haploësthes in Senecioneae.
