    Abstract:

    [Objective] The purpose is to update and supplement the background information on wild plant resources in the Micangshan Nature Reserve of Shaanxi Province, and provide a theoretical basis for the effective conservation and rational use of wild plant resources. [Methods] Combined with the identification of specimens, the review of relevant literature and books, and the consultation of experts, the new record plant specimens of Shaanxi were collated and screened.[Results] Five species of plants were identified as having their first distribution in Shaanxi, including Stachyurus himalaicus Hook. f. et Thoms, Glochidion wilsonii Hutch, Trichosanthes laceribractea Hayata, Cayratia albifolia C. L. Li and Zingiber atrorubens Gagnep. [Conclusion] The new record of plants enriches the background data of angiosperms in Shaanxi Province. The new distribution of the five plant species is of some significance for the study of their origins and range shifts.
