China is known as an important distribution center for the genus Lilium, with 55 species having been reported in the country thus far. This study was conducted to provide the first comprehensive evaluation of Lilium distribution in China. A total of 27 species of Lilium and 3 varieties were found to exist in the main centers of Lilium distribution in China; these species were identified and classified based on their morphological characteristics. The distribution and botanical characteristics of the various species are reviewed in this study. We also describe differences, mainly in flower color within the same species, which may be representative of new natural varieties or ecotypes. An analytical hierarchy process (AHP) utilizing 16 indicator characteristics was used to evaluate the collected Lilium resources based on their ornamental value, utilization potential, and ecological adaptability. L. dauricum received the highest AHP scores, indicating that it was the species best suited for sustained exploitation. In addition, L. henryi, L. rosthornii, L. tsingtauense, L. concolor var. pulchellum, L. lancifolium, and species with trumpet–shaped flowers also showed better potential for exploitation than other species. This study also provides references regarding the effective exploitation and use of wild Lilium resources.
