Abstract: The genus Rhododendron resources were rich in the Qionglai mountains. investigations were made of species, habitats and concrete distribution of rhododendrons by conducting surveys, collecting samples and photos. A total of 63 species belonging to 3 subgenus, 4 sections and 11 subsections were observed and the altitudes ranged from 1 230 m to 4 179 m. Most rhododendron species grew together in their typical habitats whereas a few species occurred fragmentally. In this study, plenty of specimens, and photos which could show characters of rhododendrons were collected to provide basic materials for further researches.
