81. Eragrostis, Beauv. Ess. Agrost. (1812), 70, pi. 14. 



f. 11 ; Cke. ii, 1021. 



1 Hitchcock ascribes the genus to Host because Hast was the first to describe 

 a species of Erogrostis (Gram. Austr. 4 (1809), 14, pi. 24). Host, however, did 

 not give a diagnosis of the genus and so we retain Beauvois who first diagnosed 

 the genus, I.e. 



Species more than 100.— Tropical and temperate regions. 



Cooke describes 15 species Of these Eragrostis cynosuroides, Beauv. has 

 been put under Desmostachya above. The other species are being retained, 

 with the exception that E. tenella, var. viscosa, Stapf is considered as a distinct 

 species (E. viscosa). Of two species the names had to be changed viz. E. 

 amabilis is here called E. unioloides, and E. maior goes under the name of E. 

 Eragrostis. E. papposa and.E. brachyphylla are new to the Presidency. 



Key, after Cooke.
