本文记述了吉林省龙井县三河镇附近清水溪的三河植物群。该植物群系由17科22属24种组成，是一个针阔叶混交林。本文仅记述了17个已知种、1个新种和6个未定种。这个植物群的物种数量虽不多，但其多样性是很明显的。此外，还将三河植物群与朝鲜的Hoeng Yeong植物区系和Kogeonwoon植物区系进行了比较。因此，建议将三河组作为一个新的地层单位。通过与亚洲第三纪其他植物群的比较，认为三河植物群的时代为渐新世。
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.
