 FESTUCA  DURIUSCULA. { Spec. Plant. 
 Hard Fescue-grass, 
 Spec. Char.  Panicle  diffuse,  branched;  floret valves  -with or without  aristae;  straw upright;  
 . leaves bristle-shaped,  and smooth. 
 F estuca  duriuscula  is  to be  found  in  most pastures,  but  especially in  those which  are  upland  or  
 dry;  we  meet with  it  in the  crevices  of walls,  and  in  the fissures  of rocks:  growing  in  maritime  
 situations,  or within the influence of the sea air, it becomes towards autumn of  a blue green hue,  and  
 is then probably the variety known under  the  name  of F. glauca.-  As  an  upland pasture grass,  
 perhaps we  have  few superior  to  the hard Fescue;  though  its  produce  is  not  abundant,  yet  in dry  
 seasons  its  foliage  is  less  injured  and wasted  than  any o f our grasses:  sheep  eat  it with  a  marked  
 avidity, and it abounding in what the grazier calls *’ proof,’ a smaller quantity of it will perhaps continue  
 existence longer than any other of our grasses.  In  low lands and meadows  it will not be  serviceable,  
 as in those situations it is comparatively insignificant  compared with the  luxuriant vegetation  o f such 
 places.____Much as this  grass will be esteemed vegetating in its required stations,  yet in  arable lands 
 it is often  a most pernicious weed:  in newly broken-up soil,  or  after  a foul tilth,  it springs up with-  
 the  com,  of a deep green colour,  distinguished by the  name  of Black-grass,  and often  in very considerable  
 patches overpowers the com,  or at least robs it of  that nutriment which it requires,  and the  
 spikes consequently become unhealthy in their look,  thin in quantity,  and the grain poor in quality.
