The taxonomy of the Microtoena insuavis complex (Lamiaceae) is controversial. No agreement on the taxonomic treatments of M. esquirolii , M. insuavis , M. mollis and M. patchoulii has been reached. In addition, some species and varieties described on the basis of a single specimen or a limited number of specimens are doubtful. Based on the examination of a large number of herbarium specimens, extensive field observations, population sampling, scanning electron microscopy observation and statistical analysis of some characters, M. esquirolii is separated from the M. insuavis complex, and M. subspicata and M. subspicata var. intermedia are treated as synonyms of M. esquirolii , M. pauciflora is treated as a synonym of M. patchouli , and M. siamica is treated as a synonym of M. insuavis . Only three species ( M. insuavis , M. mollis and M. patchouli ) are recognized in this complex. © 2011 The Linnean Society of London, Botanical Journal of the Linnean Society , 2011, 165 , 315–327.
