This article addresses the nomenclatural and taxonomic issues surrounding Amaranthus caudatus and its related taxa. Neotypes and lectotypes are designated for various names, and several names are considered as synonyms of A. caudatus. Based on morphological, cytological, and molecular data, the taxa caudatus, mantegazzianus, and gibbosus are suggested to be treated as distinct species. A new name, Amaranthus baileyanus, is proposed for A. caudatus var. gibbosus due to a previously validly published Amaranthus gibbosus.
Nomenclatural and taxonomic issues concerning Amaranthus caudatus and the related taxa are presented. Types are designated for names A. caudatus var. albiflorus (neotype at RO), A. caudatus var. atropurpureus (neotype at GH), A. caudatus var. gibbosus (neotype at RO), A. dussi (neotype at NAP), and A. edulis (lectotype at LP). Holotypes are indicated for the names A. caudatus var. pseudopaniculatus f. oblongipetalus (EA), A. caudatus var. pseudopaniculatus f. pseudopaniculatus (EA), A. caudatus subsp. saueri (PR), and Amaranthus edulis var. spadiceus (CORD). The names A. caudatus var. albiflorus, A. caudatus var. atropurpureus, A. caudatus subsp. saueri, A. dussi, and Amaranthus edulis var. spadiceus are considered as hererotypic synonyms of A. caudatus. On the basis of morphological, cytological, and molecular data, the taxa caudatus, mantegazzianus, and gibbosus are here proposed to be treated as different species. A new name-Amaranthus baileyanus-is proposed for A. caudatus var. gibbosus because of a previous and validly published Amaranthus gibbosus.
