 erect and clear of it; instead of the aniherbed hnving iwo laceratcd processes, it is 

 surrounded by a deap fringed horder; rinally instead of ihe lip beiiig perfectly 

 smooih, continuous aiid destitute of all appendages at Ihe base. it is contracted about 

 Ihe middle, below the conlraction furnished with a pair of thick lleshy lohes hollowed 

 out in ihe middle sianding erect on each side of the column, without however tou- 

 ching it; and the space belween ihese lobes formirig the very base of Ihe lip iu a

Short erect sepals of which the latera! form a small bag. a long lip renexcrt at 

 the upper half, and furnished ai ihe base with four processes of which two are thii» 

 mcmhranous auricles wiiliin ihe edge of the lip , and two much more llcshy calli 

 withiu the auricles ihemselves, distinctly limit this little genus , the species of which 

 are however very difficult lo distinguish in herbaria. The Iwo auriclcs above menlioned 

 have been hitherto mistaken both hy myself and othcrs for ihe edge iiseJf of the lip, 

 owiiig 10 iheir extreme thinness aiid ihe consequeiit difficulty of observiiig lUem iu 

 dried flowers. The generic characler in LO., p. 193. moreovcr. wrongly, .siates, Ihat 

 Ihe iaterril 8C|»ols are united to a lip, which is saccaie al tlie base. Such appeurs at 

 lirst sight lo be ihe case ; but in reality ihe base ot iho lip adhercs only lo the baso 

 of ihe column, and the sac is formed cniirely by ihe union ot ihe base of the sepals.
