Abstract： Carex as a super large genus with high species diversity in the world, 100 species of Carex have been recorded from Guangxi at present. The resources of Carex in Guangxi are still unclear, the in-depth investigations and researches are lack too. Based on specimens identification, literature research and field investigation, we systematically cleared up the early researches of Carex in Guangxi, in order to provide background data for the subsequent research and sustainable utilization. At first, the research brief histories of Carex taxonomy in Guangxi were summarized. The genus Carex in Guangxi with high endemism, we focus on 16 taxa of Carex published based on types collected from Guangxi, verify the accuracy of their type locality, supplement distribution information, and make sure that 8 species of Carex endemic to Guangxi at last. Eight newly recorded species of Carex in Guangxi are reported here, which are C. alopecuroides D. Don, C. chungii Z. P. Wang, C. hirtiutriculata L. K. Dai, C. insignis Boott, C. nubigena D. Don, C. sendaica Franch., C. sociata Boott and C. transversa Boott. The morphological feature diagnosis and voucher specimens for these newly recorded species were provided. We also discussed the species diversity, endemism, geographical distribution, and the potential utilization of Carex in Guangxi.

And the citation and geographical distribution of each species are also listed in this paper. The discovery of these new species in Guangxi not only provides new data for the study of floristic geography in Guangxi, but also has important practical significance for the precise implementation of full coverage protection of native plants.
