Notes: A specimen from NW of Doi Chiang Dao in the Northern Region (Larsen et al. 2935) is this species in a vegetative state, but the young stems, petioles and nerves of the leaves beneath are finely pilose. This has not been seen on any other material of this species, but does not warrent taxonomic recognition.
