The genus Microtoena is a lovely and enigmatic member of the mint family. This new monograph is a comprehensive taxonomic revision, based on extensive field observations, population sampling, specimen examinations, scanning electron microscopy observations, statistical analysis of characters, and molecular phylogenetic analysis. Detailed species descriptions are enhanced by 20 maps, 18 full page line drawings and numerous field photos. This is an essential reference for taxonomists, growers, breeders and horticulturalists.
