    摘要:

    对2017年11月至2022年1月报道于西藏自治区的15个兰科植物新种、77个兰科植物新记录种统计表明,绝大部分(85.9%)发现于墨脱县。该研究于2021年进一步对墨脱县野生兰科植物资源进行调查,经查阅标本和文献比对鉴定,共发现采自墨脱县的兰科植物西藏新记录属1个——叉柱兰属(Cheirostylis Blume),西藏兰科新记录种10个——巡胡石豆兰(Bulbophyllum sinhoense Aver.)、葡萄天麻(Gastrodia putaoensis X. H. Jin)、中华叉柱兰(C. chinensis Rolfe)、弯瓣大苞兰[Bulbophyllum sasakii (Hayata) J. J. Verm., Schuit. & de Vogel]、独龙石斛(Dendrobium praecinctum Rchb.f.)、直立山珊瑚[Cyrtosia falconeri (Hook. f.) Aver.]、红唇鸢尾兰(Oberonia rufilabris Lindl.)、白肋菱兰[Rhomboda tokioi (Fukuy.) Ormerod]、带唇兰(Tainia dunnii Rolfe)和绿叶线柱兰(Zeuxine agyokuana Fukuy.),其中巡胡石豆兰和葡萄天麻为2个中国新记录种。结合最新文献及野外植株形态,对以上物种分别进行了描述,提供花期照片和解剖图,并总结了新记录种与相似种之间的差异,以方便鉴别。凭证标本均存放于华东师范大学植物标本馆(HSNU)。

    Abstract:

    The statistics of 15 new species and 77 newly recorded species of Orchidaceae in Tibet Autonomous Region in 2017-2022 showed that most of them (85.9%) were found in Medog County. Here, we investigated the wild orchid resources in Medog County in 2021. After critical survey of literatures and specimens, we have found that one newly recorded genus, viz. Cheirostylis Blume, and 10 new records of orchid species, viz. Bulbophyllum sinhoense Aver., Gastrodia putaoensis X. H. Jin, C. chinensis Rolfe, B. sasakii (Hayata) J. J. Verm., Schuit. & de Vogel, Dendrobium praecinctum Rchb.f., Cyrtosia falconeri (Hook. f.) Aver., Oberonia rufilabris Lindl., Rhomboda tokioi (Fukuy.) Ormerod, Tainia dunnii Rolfe and Zeuxine agyokuana Fukuy. in Medog County. In addition, B. sinhoense and G. putaoensis were two newly recorded species in China. The description of morphological characteristics, the anatomic photos of newly recorded species, and also the differences with similar species for identification are provided based on the fresh plants and the latest literature. All the voucher specimens are preserved in the Herbarium of East China Normal University (HSNU).
