Abstract Fuentes-Bazan S., Uotila P. & Borsch T.: A novel phylogeny-based generic classification for Chenopodium sensu lato, and a tribal rearrangement of Chenopodioideae (Chenopodiaceae). — Willdenowia 42: 5–24.

Stable URL: http://dx.doi.org/10.3372/wi.42.42101 Molecular phylogenetic analysis of the subfamily Chenopodioideae of the goosefoot family (Chenopodiaceae), with the addition of matK/trnK sequences to an existing trnL-F data set, indicates that Chenopodium as traditionally recognised consists of six independent lineages. One of these, the Dysphania-Teloxys clade, had already been recognised previously as a separate tribe Dysphanieae. Of the five others, Chenopodium is here re-defined in a narrow sense so as to be monophyletic. The C. polyspermum, C. rubrum and C. murale clades are successive sisters of a lineage constituted by Atripliceae s.str. plus Chenopodium s.str. Consequently, the long forgotten genera Lipandra (for C. polysper...
