This species was described by Miquel in 1857 from a specimen from Timor. It is a synonym of Wrightia tinctoria, a species otherwise known only from India. Its appearance in Timor is a mystery and is likely to be either a mistake on the label or else a cultivated plant transported from India earlier. There are no notes on the label to indicate, or otherwise, that it was a cultivated plant. Until such time as further material is collected in Timor that matches this specimen and its status can reassessed I am not including this as a Malesian species.
