Spikelets 2-many-flowered, pedicellate, variously paniculate,, 

 rachilla articulate under the floral glumes and between the florets. 

 Empty glumes j:)ersistent, narrow, usually acutely keeled, more or lesa 

 unequal, first 1-nerved, second usually 3-nerved; floral glumes nar- 

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

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

 above, faintly 5-nerved; palea a little shorter, narrow, Avith two 

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

 apex. Styles very short, distinct. Grain enclosed in the glume 

 and palea and more or less adherent. Mostly perennial grasses, 

 usually tufted, low or tall, blades flat or conduplicate. Panicle 

 sometimes narrow, secund and strict, sometimes open and nodding. 

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

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

 species, though some authors have extended the number to 230 

 species. 



The genus is one as to Avhose limits botanists are the least

 round, without any prominent keel at least at the base, and acute
