The pollen morphology of Illicium in Taiwan, I. arborescens, I. daibuense, I. philippinense, Illicium sp., and I. tashiroi, was studied. Pollen grains of Illicium in Taiwan were monads, varied from oblate to oblate spheroid. The polar view were tricolpate or trisyncolpate. The sculpture of pollen grains was reticulate. Colpi in the pole faces was diagnostic characters of pollen grain of Illicium spp. In Taiwan. Pollen grains of I. arborescens and Illicium sp. were trisyncolpate. Pollen grains of Illicium daibuense , I. philippinense and I. tashiroi were tricolpate.
