Abstract: Sediments of palaeogene period accimilated in the Qingjiang Basin of Kiangsi province are divided into two successional formations, the upper Lingjiang and the lower Qingjiang formations. Both are mainly of lacustrine in origin. In these sedi- ments numerous spores and pollen are well preserved. The palaeogenee flora of that region is very rich, in which 147 palynomorphs of 66 families have been identified. One new genus Rutaceoipollenites and 9 new species namely Rutaceoipollenites archiacus, Sapotaceoidaepollenites tricolporatus, Lonicerapollis scabratus, Quercoidites minor, Tricolporopollenites aspidoporatus, Tricolporopollenites minutus, Boehlensipollis qing- jiangensis Poentapollenites, and Jiangsiensis are described. The palynological features of these formations are stated as follows: 1. The lower part of Qingjiang formation is characterized by the predominance of Ephedra. Because of the occurrence of Schizaoisporites, Aquilapollenites Extratri-poropollenites and pentapollenites, the age of this part is, therefore assigned to late paleocene-early Eocene, and the flora at that time seems to be of desert in nature. The climate was warm and dry. 2. The upper part of the Qingjiang formation is predominated by Tricolporopollenites minutus, Quercoidites minor and pollen' of sapindaceae and Ulmaceac, which indicates that the flora was subtropical and tropical in nature. The climate then changed to humid and hot. The age of this part is assigned to middle-late. Eocene. 3. The Lingjiang formation is predominated by the pollon of Taxodiaceae and some abundant subtropical and tropical elements. These features indicate that at that time some coniferous and broad-leaved mixed forests would have been flourishing on the hills of that region. The climate was then humid and warm. The age of the Lingjiang formation is assigned to early Oligocene.
