Note. The very great majority of the species of W. India are 

 found only in the Konkan and Ghauts. The proportion tl at I have 

 seen is unusually small, and it will be noticed also that J?. has a very 

 large number of species which were not known to -D. 



1. OBEEONIA.

 veinless, flowers minute, brick-red, dense, in a raceme 2 inches 

 long, lip 3-lobed, the middle lobe 2 divided. 



Tanna districts. Trees on the Ghauts (D.). 



F. does not refer to D. either in this or 0. Lindleyana, but there 

 seems no reason for doubting the identity of the plants described.

 fleshy brown, somewhat fa'cate, spike very dense, flowers sessile, 

 petals narrow linear, lip 2-lobed, flowers straw-coloured with orange
