Colour of the flowers '^ pale bluish " (this being very unusual 

 in the genus as far as my experience goes), the side petals Avith a 

 few greenish spots. The affinities of the species are with D* 

 Woodiiy luihi. The lubellum, which is the great mark of distinc- 



tion in all the Disperids, is of a similar type, but quite dit- 

 ferent in detail, besides which all the other parts of the perianth 

 differ. We have but two plants, all that Mr. MacOwan, who so 

 diligently explored tliat fine region, ever found. Nevertheless, 

 we hope to get it again from some of our younger friends who 

 are collecting in the mountains of the Eastern districts.
