Type designations for three names applicable to Mexican species of Dysphania (Chenopodiaceae s. str. / Amaranthaceae s. l.), and a new combination
2025
Sandoval-Ortega M.H. | Zumaya-Mendoza S.
The names Ambrina dissecta, Chenopodium incisum, and Chenopodium stellatum are taxonomically assessed and their lectotypes are designated, the specimens preserved at P and GH. These three names refer to species currently placed in the genus Dysphania, but no formal combination was published for the species earlier known as Chenopodium incisum. Consequently, we here propose the new nomenclatural combination: Dysphania incisa (Poir.) Sandoval-Ortega & Zumaya-Mendoza, comb. nov. (based on Chenopodium incisum Poir.).
