Ecology - Collections: 10. At altitudes from 500--2000 m.
Notes - This species differs from other Melastoma species by the dark brown colour of most collections, its reticulate leaves and the small brown scales on the branches. The bullate leaves connects it with the Philippinian M. bensonii, but the indument is more similar to M. malabathricum.
