Abstract

A nomenclatural study of the names in Amaranthus published by W. Roxburgh was carried out. Seven names appear to have been published by the author, three being not valid from the nomenclatural point of view (Amaranthus atropurpureus, A. fasciatus, and A. lanceofolius, nomina nuda, Arts. 38.1 and 38.2 of ICN). The remaining four names are valid and they are typified by illustrations included in “The Roxburgh Collection” at the library of the Royal Botanic Garden of Kew [Nos. 447 (lectotype of A. fasciatus), 1676 (lectotype of A. lanceolatus), and 1677 (lectotype of A. frumentaceus)] or included in the Seikei Zusetsu Agricultural Catalog (neotype of A. atropurpureus).
