We are investigating the type material of taxa described from the Bonin Islands in Japan. Some taxa require typification, because specimens have not been cited in the protologue or cited specimens included multiple collections, or because the citations contained ambiguous locality and/or collector data. In addition, an earlier lectotypification is often inadequate because of an error or lack of specific information. Recently, we designated or reconfirmed the lectotype for 10 taxa of Metachlamydeae at the Botanical Gardens section of TI. Here, the lectotype was newly designated or the type status was reconfirmed for 13 taxa based on the herbarium materials of Archichlamydeae and their related literature.
