摘　　要：文章报道了剑唇角盘兰(Herminium pugioniforme Lindl.ex Hook.f.)在西藏的新分布海拔,也是目前本物种在青藏高原分布最高海拔记录(5300 m)。剑唇角盘兰主要生长在高山流石滩溪流附近,文章对其形态进行描述并提供生境和形态特征彩色照片,其凭证标本保存于西藏自治区高原生物研究所植物标本馆(XZ,No.MDK069)。剑唇角盘兰在海拔5300 m的发现进一步丰富了兰科植物在西藏分布海拔范围,刷新了兰科植物在青藏高原生长的最高海拔纪录,对青藏高原兰科植物区系分析、多样性研究和保护具有重要的生态学意义。The highest altitudinal distribution of Herminium pugioniforme in Jiali County was reported for the first time in Tibet.It is the highest distribution altitude recorded on the Qinghai-Tibet Plateau(5300 m).The detailed morphological description and photos were also provided.The voucher specimens were deposited in Her⁃barium of the Tibet Plateau Institute of Biology(XZ,No.MDK069).The Herminium pugioniformeis was growing in such area of screes at 5300 m,and that could be the highest altitudinal record of Orchidaceae in the Qinghai Tibet Plateau.It has important ecological significance for floristic analysis,diversity research and conservation of Orchidaceae in the Qinghai-Tibet Plateau.
