| description | Nomenclatural and taxonomic issues concerning <i>Amaranthus caudatus</i> and the related taxa are presented. Types are designated for names <i>A. caudatus</i> var. <i>albiflorus</i> (neotype at RO), <i>A. caudatus</i> var. <i>atropurpureus</i> (neotype at GH), <i>A. caudatus</i> var. <i>gibbosus</i> (neotype at RO), <i>A. dussi</i> (neotype at NAP), and <i>A. edulis</i> (lectotype at LP). Holotypes are indicated for the names <i>A. caudatus</i> var. <i>pseudopaniculatus</i> f. <i>oblongipetalus</i> (EA), <i>A. caudatus</i> var. <i>pseudopaniculatus</i> f. <i>pseudopaniculatus</i> (EA), <i>A. caudatus</i> subsp. <i>saueri</i> (PR), and <i>Amaranthus edulis</i> var. <i>spadiceus</i> (CORD). The names <i>A. caudatus</i> var. <i>albiflorus</i>, <i>A. caudatus</i> var. <i>atropurpureus</i>, <i>A. caudatus</i> subsp. <i>saueri</i>, <i>A. dussi</i>, and <i>Amaranthus edulis</i> var. <i>spadiceus</i> are considered as hererotypic synonyms of <i>A. caudatus</i>. 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—<i>Amaranthus baileyanus</i>—is proposed for <i>A. caudatus</i> var. gibbosus because of a previous and validly published <i>Amaranthus gibbosus</i>. |
