Forsythia, a genus with six species, is a deciduous tree and confined to temperate areas in Asia and Europe. Forsythia pollen have been only briefly characterized by light microscope (LM) observation (WODEHOUSE, 1935; ERDTMAN, 1952; etc.). Our present knowledge of pollen morphology among East Asian species of Forsythia is scant. Here we report LM and SEM observations of pollen from four species with one variety: F. suspensa (THUNB.) V AHL, F. japonica MAKINO, F. japonica var. subintegra HARA, F. viridissima LINDL., and F. koreana (REHDER) N AKAi. These species are distributed in Japan, Korea, and China.
