OLIGOCENE SANHE FLORA IN LONGJING COUNTY OF JILIN, NORTHEAST CHINA

This paper describes the Sanhe flora found at Qingshui stream near the town Sanhe in Longjing County, Jilin Province, Northeast China. This flora comprises 24 species belonging to 22 genera within 17 families and represents a mixed coniferous and deciduous broad leaved forest. Here, only 17 known species, one new species, Zizyphus orbitofolia and 6 undetermined species are described. This flora has a great diversity of species. In addition, comparison is made among the Sanhe flora and the Hoeng yeong and the Kogeonwoon floras in North Korea. As a result, the fossil bearing strata, as a new stratigraphic unit the Sanhe Formation is suggested. Based upon comparison with other Asian Tertiary floras, the Sanhe flora is considered to be Oligocene in age.
