It has one solitary flower protruding from the base of the leaf, and 



so similar to the head of a snake with tlie jaws open, that it is difficult 

 at first sight to believe it really a flower that one looks upon. To add 

 to the deception, the small labellum is shaped like a tongue, and moves 

 up and down. The stem is strong, terete, six inches long, with one 

 long striated brown sheath in the middle ; the leaf is remarkably thick 

 and fleshy, and above four inches long ; the flower is. dull yellowish 

 brown, spotted with dull purple, and nearly three-quarters of an inch 

 long.
