Endemic. 



It is singular that this fine grass, which appears to be common at no 

 great elevation in Ceylon, should not have been found in Continental 

 India. It is intermediate in characters between the subgenera Amphi- 

 lophis and Vetiveria, having the habit of the former. What is described 

 here, and by Hackel, as glume III, is perhaps a palea of glume IV.
