 liculate inflorescence, with his Acer robustum, and therefore considered that they represented an undescribed 

 publication, however, of Acer fiabellatum I have had the opportunity to examine Giraldi's Chinese collection 

 I that Acer robustum collected by him in Shensi is identical with my Acer fiabellatum.
