A considerable genus of warm and temperate regions of the whole world, a 

 few species being cosmopolitan, and two such occur in Socotra ; the other three 

 Socotran species are old world forms of greater or less range.

A species confounded with E. poceoides, Beauv. (Agrostog. 70, t. xiv. f. 11, Poa 

 Eragrostis, Linn; Sibth. Flor. Graec. t. 73), which is, however, a large mega- 

 stachyoid species occurring in Europe, Asia, and other localities, from which, 

 however, the form of the spikclets distinguishes it. Probably many of the 

 African forms referred under that species are really this one.
