Maesaceae, a new primuloid family in the order Ericales s.l.

• Evidence from morphology and molecular sequence data from three chloroplast genes, rbcL, ndhF, and atpB, have shown that the genus Maesa constitutes an evolutionary lineage separate from the other three primuloid families, Theophrastaceae, Myrsinaceae, and Primulaceae. The new family Maesaceae is here formally recognised, its taxonomic status being changed from a subfamily of Myrsinaceae. The new family comprises a single genus, Maesa Forssk., with some 100 species of trees or shrubs; it is diagnosed by characters such as flower pedicels with two bracteoles, a semi-inferior ovary, and indehiscent fruits with many seeds. A key to the major groups of primuloid taxa is presented.
