Flueggea (including Richeriella) is revised for the Flora Malesiana area. Three species are recognized. Two of them are generally small trees and they are allopatric, F. gracilis (ex-Richeriella) being present in West Malesia and F. flexuosa in East Malesia and the west Pacific. The two subspecies of the generally shrub-like F. virosa are also allopatric, with subsp. virosa having a palaeotropical distribution ending just west of New Guinea, and subsp. melanthesoides being present in New Guinea and Australia.
