Abstract: A study deals with the flora of seed plants in dry-hot and dry-warm river valley of Jinshajiang (Jinsha River) within Yunnan and a part of Sichuan. A list of names with plant fami-lies 111,genera 427, species 748 (wild, except cultivated 172) has been established,both including variaties and forms. The number pattern of generic areal-types for this region was summarized as: 1-44, 2-127, 3-10, 4-39, 5-13,6-37, 7-29,8-47, 9-12, 10-25, 11-3, 12-7, 13-1, 14-20, 15-13. In 748 species, 73 ones to be selected as the common character species of three river valleys ( Jinshajiang, Yuanjiang, Nujiang ) and 156 ones of Jinshajiang only are the basical data of this study.

Key words: Jinshajiang
