描述了在贵州梵净山自然保护区发现的兰科Orchidaceae植物一新种——梵净山铠兰Corybas fanjingshanensis Y.X.Xiong,并绘了线描图。该新种与大理铠兰C.taliensis Tang & Wang相近,区别点在于:本新种花单朵顶生,淡红色,具深红色条纹,有较短的苞片与侧萼片,唇瓣的唇盘上无褶片。报道了该种的采集过程、生境以及该种在梵净山居群的大小和保护状况,并简单介绍了铠兰属Corybas在世界的分布情况。

Corybas （Orchidaceae）, a genus of some 100 species, is distributed from the Himalayas and southern China, through the Philippines, Malaysia, Indonesia and New Guinea, to Australia, New Caledonia, Tasmania, New Zealand and the islands of Polynesia. There are three recorded species in China, C. sinii Tang ＆ Wang, C. daliensis Tang ＆ Wang, and C. taiwanensis T. P. Lin ＆ S. Y. Leu. In this paper, a new species, Corybas fanjingshanensis from Fanjing mountain nature reserve is described and illustrated. It is related to C. taliensis Tang ＆ Wang, but differs by having rather short bract and lateral sepals and lacking lamellae on the disc. Its habitat and population size was reported in details.
