Plant fossils from four localities of Miocene strata in Taiwan were investigated. From Lilongshan flora, in Fangkang, Pingtung Hsien, leaves of 1 fern, 2 monocots and 21 dicots and seeds of 7 dicots were recognized. The flora revealed a tropic-subtropic forest. In Mafu, Kuanhsi, Hsinchu Hsien, fossil woods of 1 conifer and 2 dicots were found in tuff of Late Miocene stratum. The fossils indicated colder weather than present. Stem molds of pure forest of Cycas-like plant were collected from basal part of the Nanchuang formation of Late Miocene age in Nanchuang, Miaoli Hsien. In Kungkang tuff, Kueishan, Taoyuan Hsien, growth rings of 3 fossil woods, Taxodioxylon sequoium(Merckl.)Gothan, Bischofia sp. and Camellia sp., indicated that there was obvious seasonal change at that time. The taxa of the pollen fossil in the same locality indicated a warm temperate climatic condition.
