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

 or drooping, in a more or less braiKjlied exserted panicle, racliillu 

 articulate between the floral glumes, glabrous or scabrous-])ube.scenc. 

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

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

 keeled or convex on the back, 5-0-nerved, the hyaline apex usually 

 shortly bifid, the midrib produced into a straight or curved awn> 

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

 glume, the two jn'ominent keels usually pectinate-ciliate. Stamens 

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

 membranous apendage, the very short distinct styles more or less 

 lateral. Grain oljlong or linear, often more or less conduplicato,. 

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



Annuals or perennials, witli 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 

 very closely allied to Festnra, into which it passes imijcrceptibly 

 through F. (/i(/nnlea Vill. 



Bentliam proposed the following sections: 



1. Fcsfiiroidcs Coss. & Dur. — tall pereiuiials coming near to. 

 Festuca, with the awns usually very short or I'educed to small 

 points. 



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

 awned ijlumes.
