Spikelets 2-inany-fl()\vered, podicollate, varioui^ly ])aniculate. 

 racbilla articulate under tlie floral glimies and between tbe florets. 

 Eniptyglnmespersistejit, narrow, usually acutely keeled, more or less 

 uneqtml, flrst l-nerved, second usually 3-nerved; floral glumes nar- 

 row, membranous, cbartaceous, acute or tapering into an untwisted 

 awn or rarely obtuse, rounded on tbe back below, often keeled 

 above, faintly 5-uerved; palea a little shorter, luirrow, witb two 

 prominent keels. Stamens 1-3. Ovary glabrous or pilose at tbe

 and palea and more or less adherent. Mostly i>erenuial grasses, 

 usually tufted, low or tall, blades flat or coudui)licate. Panicle

 Tbe genus is very widely spread over the globe, especially in tem- 

 perate or mountainous regions. There are about 80 well-marked 

 species, tliough some authors have extended the number to 230 

 species.
