Pimenov&Kljuykov]、噶穆兔耳草(Lagotis kunawurensis Rupr.)。【结论】文章对以上3个中国新记录种进行报道，对于研究该地区植物组成具有一定参考价值，同时为青藏高原植物多样性保护及植物系统分类补充新资料。

Newly Recorded Seed Plants of China

The Qinghai-Tibet Plateau possesses unique and valuable plant resources due to its special geographical location, rich vegetation types and complex and variable climatic conditions. The clarification of the plant background information and geographical distribution of the region is of great importance to the study of the flora of the region. In this paper, three new record Chinese species, namely Pedicularis cornigera T.Yamaz., Hymenidium dentatum (DC.) Pimenov & Kljuykov and Lagotis kunawurensis Rupr., were discovered based on the survey of alpine plant diversity and flora in the Karma Gorge region of Tingri County, Tibet Autonomous Region. This paper reports the above three new record Chinese species, which are certain reference for the study of plant composition in this region. It further provides new information for plant diversity conservation and plant systematic classification on the Qinghai-Tibet Plateau.
