A well‐preserved fossil pollen flora from the Bose Basin located in mid‐western Guangxi, South China (long. 106°34’ ‐ 107°21'E and lat. 23°28 ‐ 23°55'N), consists of some 160 types belonging to 121 genera and 62 families. Four pollen and spore assemblages are recognized (from the bottom upward) for the Late Eocene Nadu Formation: Polypodiaceae‐Pinuspollenites assemblage, Quercoidites‐Ulmipollenites assemblage, Alnipollenites‐Tricolporopollenites assemblage, and Pinuspollenites‐Quercoidites assemblage. The pollen flora of the Bose Basin represents a mixed evergreen and deciduous broad‐leaved forest that consisted mainly of Fagaceae, Ulmaceae, Betulaceae, and Juglandaceae along with a number of subtropical to tropical evergreen trees. Relatively common occurrence of Pinaceae pollen probably indicates a conifer forest or woodland on the mountain area not far from the lowland sediment basin. This type of paleovegetation is similar to the modern mixed evergreen and deciduous broad‐leaved forest in sou...

A flora containing both plant microfossils and megafossils has been reported from four placer gold wells in Huanan County, Heilongjiang Province of north-east China. Most of the pollen and megafossil plants are in common. Families Fagaceae, Betulaceae and Pinaceae are abundant in this fossil flora which probably implies a mixed conifer and deciduous broad-leaved forest of warm temperate climate. On the basis of associated vertebrate fossils and correlation with equivalent floras a Late Miocene age has been assigned.
