ROSACEAE

For the horticultural hybrid between almond ( Prunus dulcis (Mill.) D.A.Webb ) and peach ( P. persica ( L.) Batsch), recently reported as casual alien to Italy (<http://www.floraitaliae.actaplantarum.org/viewtopic. php?t=43473&p=278405#p278405>, retrieved on 4 October 2017), after an exhaustive review of the available synonyms Rehder (1922) established the combination Prunus × amygdalo-persica (Weston) Rehder. He noted that the most ancient binomial with priority is Amygdalus amygdalo-persica Weston [1770] which however lacks description, but, in his opinion, it is usable on the basis of an earlier [1768] Duhamel’s name Amygdalo-Persica subsequently picked-up by Poiret to designate a rankless variant of Amygdalus communis L. Rehder adds: “If Weston’s name should be rejected for the reason that it lacks a description, Schneider’s P. persico-amygdala based on Amygdalus Persico-amygdala Reichenb. [1832] would be the correct name, for Schmidt’s A. hybrida [1822] [...] cannot be transferred to Prunus on account of Prunus hybrida Quetierii Carr. (sic!) [...], a supposed hybrid between Prunus Armeniaca L. and P. Persica Batsch. ”. Actually, the obstacle due to Carrière’s name (Mouillefert, 1892) does not exist according to Art. 23.1. of ICN; moreover Art. H.10.2. prevents the use of epithets made by parental epithets united by hyphen considering them formulae, not true epithets. In our case this excludes any adoption of most reported synonyms including the Rehder’s combination under Prunus (i.e., amygdalo-persica , communi-persica, and persico-amygdala ), while allows we to recover the name of Schmidt Amygdalus × hybrida as basionym.
