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.
Selected References
None.
