One of us (Chang) considers that this taxon would be better treated as a separate species, Acer grosseri, due to a different number of flowers (10-15) per inflorescence and geographic distribution (Anhui, Gansu, Hebei, Henan, W Hubei, Jiangxi, Shaanxi, Shanxi, and Zhejiang). However, one of us (Chen) does not agree.
