Resumen

A new small-flowered species of Cyrtochilum  from  the  isolated  range  of  the  Condor  mountains   in   Ecuador   is   described   and   illustrated   with   a   line   drawing   and   a   photograph   of   the   holotype.   It   shares   morphological  features  with  several  different-­looking  groups  of  Cyrtochilum,  such  as  the  two  generitypes  of   the  genus:  C.  undulatum  and C. flexuosum,  as  well  as  with  plants  in  the  C.  myanthum  complex.  These  groups   are   treated   as   three   separate   genera   by   some   (Cyrtochilum,   Trigonochilum   and  Dasyglossum, respectively),   but  the  combination  of  morphological  features  seen  in  our  new  species  brings  the  groups  together  into  one   polymorphic  but  genetically  monophyletic  genus.
