The floral anatomy of five taxa of Melastomataceae, namely, Memecylon edule, M. guinensis, M. capitellatum, Rhexia marina and Tabouchina semidecandra has been studied. The regular, epigynous flowers are tetramerous in Memecylon edule, M. capitellatum, Rhexia marina and pentamerous in M. guinensis and Tabouchina semidecandra . The floral parts as well as their traces show varying degrees of adnation. The septate condition of the ovary in Rhexia marina and Tabouchina semidecandra and the presence of rudimentary septa in Memecylon edule, M. guinensis and M. capitellatum reveal that the central placentation in the family is derived from axile or anatomically parietal ancestry. The carpels are 3‐traced in Memecylon edule, M. guinensis and M. capitellatum and 5‐traced in the rest. The style is vascularized by the dorsal bundles in Memecylon species and by the common median laterals in Rhexia marina and Tabouchina semidecandra .
