The inflorescences of this maple are relatively showy compared to most other representatives of this genus in North America. Fall color orange to red.

A closely allied species from subalpine forests of eastern Asia is Acer caudatum Wall. Pictured here is likely the subspecies ukurunduense. The inflorescence is more conical than in A. spicatum.
