摘　　要：薹草属(Carex L.)是广西物种多样性丰富的大属,目前记录的物种达100种,然而广西薹草属植物资源仍然不清楚,缺乏系统的调查与研究。该文基于馆藏薹草属植物标本鉴定,文献收集整理和野外调查等基础上,对广西薹草属植物的前期研究进行系统的梳理,对广西薹草属植物物种编目简况进行了概述;另外,广西薹草属植物特有性高,通过对16个模式标本采自广西的类群进行系统梳理,考证其模式产地准确性,补充分布信息,确定目前广西特有薹草属植物共8种;报道了广西薹草属植物8个新记录种,即禾状薹草(C.alopecuroides D.Don)、仲氏薹草(C.chungii Z.P.Wang)、糙毛囊薹草(C.hirtiutriculata L.K.Dai)、秆叶薹草(C.insignis Boott)、云雾薹草(C.nubigena D.Don)、仙台薹草(C.sendaica Franch.)、伴生薹草(C.sociata Boott)、横果薹草(C.transversa Boott),提供其形态特征集要与凭证标本照片,并对广西薹草属植物的多样性、特有性、地理分布以及资源潜在利用价值等进行了讨论,该研究结果为薹草属的后续研究与利用提供了本底资料。Carex L.as a super large genus with a high species diversity in the world,100 species of Carex have been recorded from Guangxi at present.However,the resources of Carex in Guangxi are still unclear,and lack of research and investigation.Based on specimens identification,literature research and field investigation,we systematically cleared up the early researches of Carex in Guangxi,and summerized the research brief histories of Carex taxonomy in Guangxi.The genus Carex in Guangxi with high endemism,we focused on 16 taxa of Carex published based on types collected from Guangxi,verified the accuracy of their type locality,supplement distribution information,and made sure that eight species of Carex endemic to Guangxi.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 are provided.We also discussed the species diversity,endemism,geographical distribution,and the potential utilization of Carex in Guangxi.The results provide background data for the subsequent research and sustainable utilization of Carex.
