摘要
【目的】文章报道了在云南省发现的兰科植物纤弱天麻(Gastrodia exilis Hook.f.)为中国新记录,比较和归纳了其形态近缘种勐海天麻(G.menghaiensis Z.H.Tsi&S.C.Chen)、葡萄天麻(G.putaoensis X.H.Jin)和白花天麻(G.dyeriana King&Pantl.)的分类特征。【方法】使用体视显微镜对上述物种野外居群标本进行解剖观察,并用接驳微距镜头的数码相机进行拍摄记录。【结果】纤弱天麻唇瓣与花被筒分离,唇瓣前部表面有2个明显的三角形薄纵脊,花被筒裂片先端撕裂状,易于区分。【结论】纤弱天麻是中国新记录兰科物种,该发现扩大了其分布区,也进一步丰富了中国植物资源和生物多样性。
[Objective]A newly recorded orchid species,Gastrodia exilis Hook.f.,was spotted from Yunnan Province,China,and its main characters were compared with its morphologically close relatives G.menghaiensis Z.H.Tsi&S.C.Chen,G.putaoensis X.H.Jin and G.dyeriana King&Pantl.[Methods]Morphological and anatomical observations of wild population specimens of the above species were carried out using a stereomicroscope,and photographs were taken with a close-up lens attached digital camera.[Results]G.exilis Hook.f.could be easily distinguished from those species by having a lip free of perianth tube,a disk with two conspicuous triangular lamellae near apex,and lobes of perianth tube crisped.[Conclusion]G.exilis Hook.f.is a newly recorded orchid species in China,and the discovery expands its distribution area and enriches the resources of wild orchids in China.
