Two new species of Scutellaria (Lamiaceae), S. tenasserimensis A. J. Paton and S. khaoyaiensis A. J. Paton, are described here. The name S. cana Wall. ex Benth., recognised as a synonym of S. repens D. Don, is based on specimens belonging to S. repens and S. tenasserimensis. S. cana is lectotypified to clarify the division of these two species. A key to the Scutellaria species of Thailand is provided and the relationships of the species and the relevant morphological characters, particularly nutlets, are discussed.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS10.1007/s12225-016-9620-2
