FESTUCK.E. ^8'S 



or awned at the end, and by tlie glabrous grain adhering to the 

 jialea. Hut there are exceptions to eaeli of these characters ; some 

 species run very much into Puu and Alropin, others into /Irnmtts. 

 If we had only European species, Vulpia might well have been 

 retained as a geiuis; but in some of the South American s])ccies the 

 panicle is loose, the awn sometimes very short ami the inflorescence 

 rather that of Eufedma. Jienthum proposed as sections tho 

 following: 



1. Vnlpia (Gmel. as a genus). 



2. Eiiffstura. Panicle loose, spreading or narrow, empty ghnnes 

 nearly equal, iloral glumes acute or muoronate; stamens 3, anthers 

 and stigmas iirojecting from the glumes at the time of flowering: 

 ])erenniuls. 



;J. SrhedoHorufi (Reauv. as a genus). Panich^ loose, narrow or 

 spreading, glumes awnless and the grain quite free from the palea. 



4. C((t(ipii(liiitn (Link, as a genus). Infloresceiu'e nearly simple, 

 like that of llordew, but the racliis not notohe*!, aiid the spikelets 

 not quite sessile, the lower ones of ten two or three together on a very 

 short branch. 



5. Sclcropfid (fSriseb. as a geinis). 



I have lu'arly followed E. Ilackel in the selection and use of 

 the sections of Fesluca, believing them preferable to those given by 

 Bentham or others.
