摘　　要：【目的】文章报道了中国兰科玉凤花属一新记录种龙须玉凤花(Habenaria trichosantha Lindl.),提供花期照片和解剖图,并总结了其与形态近缘种之间的差异。【方法】对该物种国内野外居群植株进行了形态观察,并拍摄记录主要分类特征。【结果】龙须玉凤花过去记录分布于东喜马拉雅和中南半岛区域,现发现于滇西海拔800~1000 m的怒江干热河谷稀树灌木草丛中;其主要识别特征为唇瓣侧裂片扇形轮廓,并分裂为具有二次分枝的长流苏,明显有别于其他同属物种。【结论】龙须玉凤花是中国新记录物种,本发现进一步丰富了中国野生兰科植物资源。[Objective]This paper reports the first occurrence of Habenaria trichosantha Lindl.(Orchidaceae)in China.Detailed anatomic photos at blooming period are provided and the differences with its morphologically close relatives are summarized.[Methods]Morphological observation of wild population plants of this species in China was carried out,and the main taxonomic features were photographed and recorded.[Results]H.trichosantha Lindl.was only recorded in the Eastern Himalayas and Indo-China Peninsula historically. It is found in the Savanna ecosystem of the dry-hot valley of Nujiang in westernYunnan. The most recognizable feature of its flower is the fan-shaped outline of the lateral lobe of the lip,which is divided into long tassels with secondary branches. Thus, it is easily distinguished from other speciesof the same genus. [Conclusion] H . trichosantha Lindl. is a newly recorded species in China, whichfurther enriches the resources of wild orchids in China.
