N. B. When the flower is turned upfide down, 

 the calyx appears to consist of four leaves 

 only, but then the two outer leaves are 

 larger than the rest and connected, so as 

 to form a sort of helmet, beneath which 

 the labellum is fixed in a pendent situation. 

 Though remote from the Style, it, however, 

 communicates with it by means of a kee! 

 running from it to the end of the connected 

 leaves of the calyx. Thus the flower of 

 this genus appears almost like that of 

 Cranichis.
