Abstract：The Eriobotrya Lindl. flora and its geographical distribution in Yunnan were studied based on the literature,herbarium specimens and field investigation. The results show that there are 16 species or variants in Yunnan, among which 13 are species accounting for 81.25% of the total 16 species in China, and the rest 3 are variants accounting for 60% of the total 5 varieties in China. Among them, E. elliptica Lindl. was found in Yunnan for the first time. Based on the vegetation,natural conditions and the distribution features of Eriobotrya in Yunnan province, its geographical distribution can be divided into 4 regions: Regions Ⅰ covers southern and southwestern Yunnan; Regions Ⅱ includes southeastern Yunnan; Regions Ⅲ is central plateau; and Region Ⅳ covers Western and northwestern Hengduan Mountain range. Compared with the neighboring regions or countries, Yunnan has the richest germplasm resources of Eriobotrya. The above analysis suggested that Yunnan province is a distribution center as well as a gene center of Eriobotrya in China.
