中国兰科二新记录种

Two newly recorded species(Orchidaceae)in China

兰科植物资源调查是掌握地区兰科本底资料的基础,对研究兰科植物的地理分布和资源多样性具有重要意义。该文报道了分别产自中国西藏自治区墨脱县和巴宜区的石豆兰属(Bulbophyllum Thou.)中国分布新记录种——尼泊尔大苞兰(B.raskotii J.J.Verm.,Schuit.&de Vogel)和曲唇兰属[Panisea(Lindl.)Steud.]中国分布新记录种——林芝曲唇兰(P.panchaseensis Subedi)。此二新记录种均生长在海拔约2000 m的常绿阔叶林中的树干或岩壁上。此外,还提供了二新记录种的形态特征描述和彩色图片等信息,并附有国产曲唇兰属的分种检索表。该研究结果扩充了我国兰科植物的记录,为我国兰科植物多样性和保护研究提供了新资料。

Orchidaceae resources census is the basis of mastering regional background data,and it is of great significance to the study of the geographical distribution and resource diversity of Orchids.Two newly recorded species of Orchidaceae,Bulbophyllum raskotii J.J.Verm.,Schuit.&de Vogel and Panisea panchaseensis Subedi,are reported from southeastern Tibet,China for the first time.They grow on trees or rocks in evergreen broad-leaved forest at elevations of 2000 m.Descriptions and photos for diagnostic characters are provided.Key to Panisea species occurring in China is provided.This study enriched the records of Orchidaceae in China,and provided basic data for studies of Orchidaceae diversity and conservation.
