Taxonomic studies of Brazilian Meriania species (Merianieae -Melastomataceae) have identified taxonomic and nomenclatural gaps. The present work proposes one new synonym, M. sanchezii, for M. paniculata; one new neotypification of M. glabra; and five lectotypifications for M. calophylla, M. glabra var. parviflora (= M. glabra), M. paniculata, M. pergamentacea (= M. robusta), and M. urceolata.
