The species of ihis well-marked genus are undistinguishable in a dried state , un- 

 less attention is paid to the processes which appear upon the surface of the lip. The 

 not knowing ihis and the badness of materiais led to a very imperfect set of de- 

 finitions in L.O.. as was indeed hinted in a note to ihat work. Eyen uow ihe species. 

 require to- be studied carefully in a live stale.

 This specics is distinguished by two circumstances : the scape is longer, tlian ihe 

 leaves, and ihc lip is acute. I have seen no specimen. Roxburgh says, that ihc spike 

 is oblong and pendulous, wiih distant flowers of a beauliful rose-colour.
