Alnus henryi C.K.Schneid., Pl. Wilson. 2: 495 (1916).

A.K.Skvortsov, Grimshaw & Bayton, 2009 indicate that Alnus henryi is poorly known and very similar to Alnus formosana, and note that further studies may show that they are conspecific. The only major difference between the two appears to be one of phenology: A. formosana flowers in spring, while A. henryi flowers in autumn.
