Though Weston gives no description of his Amygdalus Amygdalo- 

 Persica it is clear that his name must be based on Duhamers name "Amyg- 

 dalo-Persica" published two years earlier. 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. would be the 



1 Poiret cites Duhamers name as one of the varieties of Amygdalus communis with- 

 out making a varietal combination. Duhamel's name must be considered pre-Lin- 

 ncan, as are the following: Amygdalopersicus Camcrarius, Hort. Med. Philos. 14 

 (1588). — Persica amygdaloides Bauhin, Pinax, 440 (1623). — Amygdalo-persica Du- 

 hamel, Arb. Fruit, i. 127, t. 4 (1768). — Under the name u Amandier-Pecher" it has 

 been figured by Noisette, Jard. Fruit, t. 3, fig. 1 (1821) and by Jaume St. Hilaire, Fl. 

 & Pom. t. 368 (1830?), and as i 'Peach-almond hybrid" by Leonard Coates in Jour. 

 Hered. xn. 327-328 (habit of tree and fruits) (1922.) 



2 Reichcnbach quotes Dalechamp as author of this combination but- I have not 

 been able to find that name in the Historia generalis plantarum of that author, only 

 "Persica Amygdala'" occurs there of which I am not sure if it belongs here. 



3 Mouillefert cites " Amygdalus persicoides Nouv. Duham." in the text (p. 391) as 

 a variety of A. communis without, however, using a varietal combination; on the plate 

 the name appears as "A. persicoides Decne". — In Index Kewensis C. Koch is cited as 

 the author of this combination, but he only quotes " Persicoides Ser." as one of the 

 synonyms of the u Mandelpfirsich oder Pfirsichniandel" which he refers to Amygdalus 

 Persica as a form.
