Qercus sect. Heterobalanus. a section of sclerophyllous oaks in high elevation of East Asia. are mainly distributed in the HimalayaHengduan Mountains （HHM） and the mountain tops of East China. The high quality of the fossil record and present distribution in the HHM region and eastern China indicate that Quercus sect. Heterobalanus is an ideal rnodel for the study of the evolutionary response to both geological and environmental changes of the HHM as well as the other regions.
