Pyrostria is a genus of dioecious flowering plants in the family Rubiaceae. Most of the species are endemic to Madagascar, others occur on islands in the western Indian Ocean (Mauritius, Comoros, Réunion, Rodrigues, Socotra), a few are found in continental Africa, and only six species occur in tropical Southeast Asia. The formerly recognized genus Leroya, containing two species endemic to Madagascar, L. madagascariensis and L. richardiae, was sunk into synonymy with Pyrostria.
