Summary

A revision of the genus Gmelina L. (Lamiaceae) is presented with a summary of its taxonomic history, keys, full descriptions, distribution maps, conservation assessments, ecological information and ethno-botanical notes. For the New Caledonia species no descriptions and distribution maps are given as they have been provided in an earlier publication. In this treatment, 31 species are recognised, 18 names are placed into synonymy for the first time, five are lectotypified, one is neotypified (G. racemosa (Lour.) Merr.) and seven names are excluded from the genus. Two varieties (G. palawensis var. palawensis and G. palawensis var. celebica) are raised to subspecies level. Four new species are described: G. australis de Kok, G. basifilum de Kok, G. hollrungii de Kok and G. peltata de Kok.
