Spikelets sevenil-lloworod, paniculate, racliilla articulate above 

 the empty glumes ami between the llorets, hairy rouiul them or gla- 

 brous, llowers perfect or the upper ones male. Kmjjty glumes firm, 

 acute, uuawneil. l-U-nerved, keeled, glabrous or the keel, scabrous- 

 ■ciliate; iloral glume uiuiwued, the lower part rounded on the back, 

 more or less o-nerved at first, often hardened and nerveless in fruit, 

 with 3 terminal l-;J-nerved lobes or teeth; palea broad, about as 

 long as the entire ])art of its glume, with two i)rominent nerves. 

 Stamens 3. Ovary glabrous, styles very short, distinct. (J rain 

 sonu'what dorsally compressed, enclosed by glume and palea but 

 not adherent. 



Perennial grasses, often firm and branching or stolonifei-ous at 

 the base; blades narrow, firm, often involute. Panicles narrow 

 and simple, with few si)ikelets, or ample like those of numy species 

 of E ray runt i,t. Spikelets mostly erect. 



There are ii\y.>'A 20 species, mostly found in temperate regions of 

 Europe, America. Africa, Australia. It has the typical characters 

 of the tribe without the ])eculiarities of the other genera, the lobes 

 of the floral glume reduced to short teeth or points, or the central 

 one sometimes lengthened into a short awn. 



Four sections liave been proi)osed : 



1. I sot via, — three lobes of the floral glume narrow, lanceolate, 

 and equal. 



2. Vralepsia {SieffJinf/la liernh., Men'sarhne'Vyhi.). — the lateral 

 teeth of the glumes broad and not pointed, and sometimes very 

 minute. 



3. Tricnspis Beauv. ( Wimhoria T^'utt.), — nerves of the lateral 

 teeth produced into short points. 



4. Lcptorarydion llochst.. — the dense soft panicle almost of 

 TrirJilorix, but with the sjjikelets of Trimlia.
