Cavanillea Medikus; Sidanoda (A. Gray) Wooton & Standley

Herbs or subshrubs, annual. Stems erect to decumbent, hispid or stellate-hairy to glabrescent. Leaves: stipules deciduous, inconspicuous, usually linear; blade usually linear, lanceolate, oblong, or ovate to triangular, sometimes lobed, base truncate, cordate, or cuneate, margins dentate to entire. Inflorescences axillary solitary flowers or terminal racemes or panicles; involucel absent. Flowers: calyx accrescent or not, not inflated, ribbed or not, base rounded, lobes ovate to triangular, apex acute or acuminate; corolla yellow, lavender, or purplish, rarely white; staminal column included; style 5–19-branched; stigmas usually abruptly capitate. Fruits schizocarps, erect, not inflated, oblate, not indurate, hairy; mericarps 5–19, 1-celled, with or without spur at dorsal angle, lateral walls usually disintegrating at maturity, irregularly dehiscent. Seeds 1 per mericarp, sometimes enclosed in persistent reticulate endocarp. x = 15.

Species 23 (7 in the flora): North America, Mexico, West Indies, Central America, South America, Australia.

Anoda is predominantly Mexican in both distribution and maximum diversity, the South American occurrences being predominantly of the weedy A. cristata.
