Abstract
As part of the ongoing studies of the genus Amaranthus Linnaeus (1753: 990) and in the course of the preparation of a new checklist of the vascular plants alien to the flora of Italy (see e.g., Iamonico 2015, 2016; Galasso et al. 2016, 2018), following the checklist of vascular plants native to Italy (Bartolucci et al. 2018), we present here a note regarding some names applied to hybrids of Amaranthus.
