 Stems very slender, much geniculately branched, glabrous ; nodes 

 pubescent. Leaves 1-1| by |-| in., ovate, broadly amplexicaul, caudate- 

 acuminate with setaceous tips, glabrous or sparsely hairy on both sides,

 well as the nerves scabrid ; upper invol.-glume as long as the lower, 

 obovate-oblong(when spread out), obtuse, emarginate,apiculate, 3-nerved, 

 hardly keeled, nearly smooth ; lower floral glume (or palea of upper 

 floral glume) shorter than the upper invol.-glume, lanceolate ; awn basal,

There is a single and not very good specimen in Herb. Kew. collected by 

 Woodrow and ticketed " Deccan." I have seen no other. The grass seems to be 

 procurable at Matheran and Mabableshwar, both places of easy access, and a few 

 specimens would be highly acceptable at Kew.
