Spikelets several -flowered, oval to lanceolate, pedicellate, erect 

 or drooping, in a more or less branched exserted panicle, rachilla 

 articulate between the floral glumes, glabrous or scabrous-pubescent. 

 Empty glumes unequally acute or fine-pointed, unawned, 1-5- 

 nerved or the second with a very short awn ; floral glume longer, 

 keeled or convex on the back, 5-9-nerved, the hyaline apex usually 

 shortly bifid, the midrib jiroduced into a straight or curved awn, 

 free from or little below the apex; palea nearly as long as the- 

 glume, the two prominent keels usually pectinate-ciliate. Stamens 

 3. or rarely fewer. Ovary obovate or linear, crowned by a hairy 

 membranous apendage, the very short distinct styles more or less 

 lateral. Grain ol^long or linear, often more or less conduplicate, 

 adhering to the palea or more or less to the base of tlie floral glume. 

 Annuals or perennials, Avith flat blades, the sheaths often closed. 

 The genus is a fairly natural one, widely distributed over the tem- 

 perate regions of the globe, and contains about 40 species. It is 

 vei-y closely allied to Festuca, into which it passes imperceptibly 

 through F. gigantea Vill. 



Bentham proposed the following sections: 



1. Fcsturoides Coss. & I)ur. — tall perennials coming near to 

 Festuca, with the awns usually very short or reduced to small 

 points. 



2. Stenohro7niis Griseb. — mostly annuals, with narrow long- 

 awnod illumes.
