摘　　要：本文报道了采自西藏喜马拉雅南坡的8个中国种子植物新记录种以及1个西藏新记录属。前者分别是吉隆牛奶菜(Marsdenia roylei)、塔基棕榈(Trachycarpus takil)、喀西蜂斗草(Sonerila khasiana)、旋花锡生藤(Cissampelos convolvulacea)、吉隆角盘兰(Herminium edgeworthii)、尼泊尔西番莲(Passiflora napalensis)、椭穗姜花(Hedychium ellipticum)和藏南象牙参(Roscoea brandisii);1个西藏新记录属为箭药藤属(Belostemma)(箭药藤Belostemma hirsutum)。凭证标本存放于中国科学院西双版纳热带植物园标本馆(HITBC)和西藏自治区高原生物研究所标本室(XZ)。Aims:The Himalaya contains many V-shaped valleys owing to the steep slopes,these valleys add to the flora and vegetation diversity.To better understand flora diversity and vegetation structure of the south slope of the Himalaya,especially the top five valleys(Yadong Valley,Chentang Valley,Gama Valley,Zhangmu Valley and Gyirong Valley),we conducted the investigation in the top five valleys July to August 2021.Methods:In this study,1,490 specimens were collected and photographed through field investigation,made into specimens,and sorted out and identified.The voucher specimens for each reported species were preserved in the Herbarium of Xishuangbanna Tropical Botanical Garden(HITBC),Chinese Academy of Sciences and Herbarium of Tibet Plateau Institute of Biology(XZ).Results:Eight species,Marsdenia roylei,Trachycarpus takil,Sonerila khasiana,Cissampelos convolvulacea,Herminium edgeworthii,Passiflora napalensis,Hedychium ellipticum and Roscoea brandisii are reported as newly recorded species from the south slope of the Himalaya in China.One genus,Belostemma(Belostemma hirsutum)is reported as newly recorded genus in Xizang Autonomous Region.Conclusions:The south slope of the Himalaya harbors one of richest floras in Xizang.But the floristic survey in this area is still insufficient,and should be further strengthened in the floristics and specimen collection in the future.
