Abstract:By the fourth survey of Chinese medicinal resources in Jiali County and Mangkang County of Tibet Autonomous Region, a Rhodiola plant was discovered on the limestone of bushes at an altitude 4,000-5,000 m, which is morphologically similar to Rhodiola humilis (HK. f. et Thoms.) S. H. Fu, but it is unique characteristics in inflorescence aterminal cymose, flowering stems closed to 7-13 branches, caudex leaves apex acute, sepals long triangular, apex organs of leaves and sepals dark pink finely mammilla, et. al, which is not same as R. humilis. Molecular biology evidence indicates that phylogeny is associated with R. humilis and Rhodiola smithii (Hamet) S. H. Fu. Based on morphological and molecular biological evidence, we described it as a new variety, named [ Rhodiola humilis (HK. f. et Thoms.) S. H. Fu var. jialiensis H. Wang, X. Z. Lan & H. P. Deng].
