Abstract:Bletilla striata is commonly used to traditional Chinese medicine in China． With the decreasing of wild resources£¬
and lack of artificial plant production£¬ Bletilla striata is in short supply on the market£¬ and it is expensive£¬ its adulterants increase
gradually£¬ but until now the lack of detailed character and microscopic studies． In this study£¬ through the research on several
times of medicine market survey£¬ collect market true bletilla and six kinds of its common adulterants£¬ using the macroscopic and
microscopic methods£¬ emphasizing characteristics of Bletilla striata surface and transection． We have studied these medicinal ma-
terials in detail of the macroscopic characters such as surface color£¬ texture and the microscopic characters such as epidermal
cells£¬ mucilage cells£¬ vascular bundle type． The result turns out that the characters which we have studied have large differences
in different varieties． Using the macroscopic and microscopic methods can well identify authenticity Bletilla striata． Using this
method can provide reference for market supervision and inspection．
Key words: Bletilla striata; Counterfeit species; Character identification; Microscopic identification
