                 Abstract: The present study analyzed the listed rare and endangered plants on List of National Key Protected Wild Plants
                 in China (2021) and List of Key Protected Wild Plants in Zhejiang Province (2023) (to be announced)ꎬ which are
                 known to occur in Zhejiang Province and their patterns of distribution. Using the coefficients of endangermentꎬ genetic
                 valueꎬ and species valueꎬ priority protection of rare and endangered plants in Zhejiang Province was quantitatively
                 analyzed. The results were as follows: (1) A total of 333 rare and endangered species belonging 229 genera in 101
                 families had been documented as occurring in Zhejiangꎬ of which 311 species (accounting for 93.39%) were seed
                 plants. The family Orchidaceae had the greatest species richness with 56 species in 32 genera. (2) At the regional levelꎬ
                 the highest densities of rare and endangered plants in Zhejiang were mainly concentrated in the Tianmu Mountain area
                 (including 147 species) in Northwest Zhejiang and the Donggong Mountain area (including 164 species) in Southwest
                 Zhejiangꎬ whereas fewer rare and endangered plant species were distributed in the plains of North Zhejiang. (3) Based
                 on elevationꎬ the distribution of rare and endangered species revealed a reversed “U” ̄shaped pattern of firstly increasing
                 with increasing elevation and then decreasing as the elevation continued to increase. The largest number of rare and
                 endangered species (144 in 113 genera of 60 families) was found at elevations 601 m to 800 m above sea level. (4)
                 According to the quantitative analysis of priority protectionꎬ 82 species (24.62%) were classified as requiring the first
                 level of priority protection (I)ꎬ and 144 (43.24%)ꎬ 85 (25.53 %)ꎬ and 22 (6.61%) species were classified as levels
                Ⅱꎬ Ⅲꎬ and Ⅳꎬ respectively. It is a species richness of rare and endangered plants in Zhejiang Provinceꎬ and this
                 analysis provides a more intuitive reflection of urgent need for a specific degree of protection for various species. The
                 current status of each species is roughly consistent with the resultsꎬ and it is necessary to strengthen monitoring for
                 proposing dynamically adjustments of the priority protection order for rare and endangered plants.
