Notes:—In the protologue of Hibiscus tiliaceus Linnaeus var. heterophyllus, Nakai (1914b) strictly cited no specimens. Three specimens, which were labeled as “var. heterophyllus Nakai ” in Nakai’s handwriting, were found in TI. Of them, the collecting year of two of the specimens is unknown, but they can be considered to have been collected before 1914, the publication year of the protologue, based on the investigation of an old label head of herbarium TI and the handwriting ( Murata et al. 2012). We regarded the three specimens at TI as the original material, and we designated the specimen with a collecting date of “ 7 March 1879 ” (TI [03424]) as the lectotype.
