摘　　要：东喜马拉雅是生物多样性热点地区,研究区域生物多样性具有重要意义。2020~2021年期间,通过调查发现了分布于西藏自治区墨脱县鸢尾兰属(Oberonia Lindl.)的1个中国新记录变种,即宽瓣显脉鸢尾兰(O.acaulis var.latipetala Chowlu,Nanda&A.N.Rao);以及2个西藏新记录种,即锯瓣鸢尾兰(O.prainianaKing&Pantl.)、棒叶鸢尾兰(O.cavalerieiFinet)。凭证标本均存放于西藏农牧学院标本馆(TAAHUC!)。这些新记录种的发现,不仅进一步扩充了西藏自治区墨脱县兰科植物的记录,同时表明墨脱县植物资源不仅与喜马拉雅地区有着紧密联系,还与印缅地区、东南亚及我国华南地区有着一定关联。The region of Eastern Himalayas is renowned for its high biodiversity and holds significant importance for understanding regional species diversity.During the years 2020 to 2021,a comprehensive investigation in Medog County,Tibet Autonomous Region,led to the discovery of a new Chinese record variety of the genus Oberonia Lindl.,designated as O.acaulis var.latipetala Chowlu,Nanda A.N.Rao.Additionally,two previously unrecorded orchid species,namely O.prainiana King Pantl.and O.cavaleriei Finet,were also found in Tibet.The voucher specimens for these findings are securely preserved in the Herbarium of Tibet Agriculture and Animal Husbandry University(TAAHUC).These newly recorded species not only enrich the orchid records in Medog County,Tibet Autonomous Region but also signify the intricate botanical connections between the plant resources in this region and neighboring areas,including the Himalayas,India-Myanmar,Southeast Asia,and South China.
