Aciiulis, racemosa. pseudobulbis oblongis alle sulcatis, foliis geminis 

 tricostatis nitidis in petiolum angustalis , bracteis setaceis, sepalis late- 

 ralibus falcatis acuminatis sub apice carinatis petalis duplo minoribus, 

 obtusis apice plano convexis, labello oblongo obsolete trilobo apice car- 

 noso concavo rotundato extus scabriusculo, tuberculo lineari apice ob- 

 tuse tridentalo. 



At flrst sight ihis species might bc mistaken for bractescens , but its flowers are 

 sraaller; ibe bracls very small and setaceous , and the lip of quite anoiher form. It 

 has little beauty. and was found in Guattmaia by Mr. Hartweg, by whom it was sent
