Notes
Collections from low altitude, previously described as D. pseudofagineus generally, have longer leaves with more nerves, are generally glaucous beneath, and have fruit calyx ribs confined to the distal half. There is no discontinuity in the variation between the lowland and hill forms however and these species are therefore not regarded as distinct here.
