Unispecific Septogarcinia from Indonesia is clearly related to Garcinia, but it was considered sufficiently distinct to warrant generic status. Septogarcinia sumbawaensis Kosterm. was sampled in a recent phylogenetic study of Clusiaceae and became nested within Garcinia, with which it shares several morphological features. Therefore, a new combination, Garcinia sumbawaensis (Kosterm.) Medellín-Zabala & L. Marinho, is proposed here.
