40 families, 54 form genera and 84 taxa of angiosperm grains are reported. Twelve form genera, 80 form species and one form variety are here described for the first time in Taiwan. In order to facilitate the identification of the Miocene Angiosperm palynomorphs, thus far found in Taiwan, a key to the genera is provided. In addition, a short note for the genus, Pterisporis Huang, 1978 of the fern spore genus is emendated.
