Diospyros balfouriana Diels

The protolog of Diospyros balfouriana describes the calyx lobes as distinctively unequal but the type specimen in E shows them to be equal.

The high altitude, small leaves and lines of hairs on the corolla suggest a possible affinity to Diospyros yunnanensis and D. dumetorum. There seems little to suggest an affinity to the D. kaki/D. lotus complex.
