A new species of banana (Musaceae), Musa nanensis Swangpol & Traiperm, from Nan, Thailand, is described and illustrated. Based on vegetative features, M. nanensis could be superficially categorized as related to M. laterita; however, it possesses several unique floral characters from the rest of the genus Musa, especially its six tepals and anthers, each fused at the base. A key to banana species of northern Thailand, based on morphology, is provided. The plant was found in a single location and is threatened with extinction due to heavy deforestation in the region.Mahidol UniversityAgricultural and Biological SciencesBiochemistry, Genetics and Molecular BiologyArticleSCOPUS10.1600/036364415X688790
