Authentic material of Diospyros changii has not been seen by the authors, but there is very little in the protolog to suggest that this species is anything but an unusually vigorous form of D. howii. Diospyros changii has many similarities to the Indochinese species D. eugenii Lecomte which however is reported to have male flowers with 16 stamens.
