<jats:p>As part of the studies on Amaranthaceae Juss. (e.g. Iamonico 2014, 2015, Sánchez Del Pino &amp; Iamonico 2016), and the preparation of the new Checklist of the Italian vascular alien Flora (Galasso et al. 2016), I present here a note on an Amaranthus hybrid which was reported for Italy by Cacciato (1966) as “Amaranthus ×galii Sennen &amp; Gonzalo” (Sennen 1929: 34). This name was proposed by Sennen &amp; Gonzalo (l.c.) without a diagnosis, and it is a nomen nudum and invalid under Art. 38.1 of the ICN (McNeill et al. 2012). Furthermore, Sennen &amp; Gonzalo in Sennen (1929: 34) cited Amaranthus patulus Bertoloni (1837: 19) and A. retroflexus Linnaeus (1753: 991) as parental taxa of the new hybrid. According to the current knowledge (see Iamonico 2016), A. patulus is a heterotypic synonym of A. hybridus Linnaeus (1753: 990). Consequently, the hybrid concept of Sennen &amp; Gonzalo refers to A. ×ozanonii (Thellung 1914: 263) Schuster &amp; Goldschmidt in Ascherson &amp; Graebner 1920: 20) (= A. hybridus × A. retroflexus).</jats:p>
