A phenological spectrum was presented for 64 tree and shrub species occurring in the primary forests and 33 other woody and herbaceous species in Chichijima Island. Long leaf flushing period in some species, flowering and fruiting occurring more than twice a year in several species and large intraspecific variations of phenology in many species indicated the tropical characteristics of phenology, while the phenological feature in the temperate zone was shown by some winter deciduous species. Three types of forest in the island, i.e. dry, rather dry and mesic forests, were different in phenology ; Leafing and flowering occurring from April to September were noticeable in the mesic forests with no droughty period, while the ratio of summer activities decreased and that of the phenological behaviors found from October to April increased in the dry forests with arid condition in the midsummer. Discrepancies in flowering time were observed among the congeneric species in some genera.
