Remarks

Note that Polyalthia sumatrana var. macrocarpa was described from a mixed collection. Fruiting material of Monoon anomalum was confused with foliage of Maasia sumatrana . As the diagnosis focused on the characters of the fruits, we here designate the fruiting material as lectotype and exclude the foliage material.
