ORCHIDACEM 73 



cose keels, one on each side. Flowers greenish. Labellum paler 

 than the sepals and petals, lateral lobes nerved with brown, the 

 apical lobe stained near the base with the same color. 



C. chloroptera has been referred to the section Filiferse, but, 

 in my opinion, wrongly. It is closely allied to C. sparsa and C. 

 lentigbiosa, differing from them mainly in its erect or ascend- 

 ing scapes. While it does not conform to the definition of the 

 section Flaccidae, to which C sparsa belongs, nor to the sec- 

 tion Erectae, on account of its linear petals, still it seems to 

 belong most naturally in the Erectae, and to this section I refer it 

 here.
