Chenopodium Linnaeus. Common name: Goosefoot, Lamb's-quarters, Pigweed.
A genus of about 140 species, herbs, shrubs, and small trees, of nearly cosmopolitan distribution. The genus (as traditionally circumscribed) has been determined to be paraphyletic (unless Atriplex is included, leading to the segregation of several monophyletic genera (Fuentes-Bazan, Mansion, & Borsch 2012; Fuentes-Bazan, Uotila, & Borsch 2012). We follow the taxonomic scheme with recircumscribed genera.
