 Gene. Char.  Calyx with two valves,  and with several florets;  arista from the back of the  
 blossom,  and twisted.  Gen., Plant. 
 AVENA  FLAVESCENS. 
 Yellow Oat-grass. 
 Spec. Char.  Panicle  expanding;  spikets very small,  not pendent;  florets  about  three  in  
 each calyx,  with aristae. 
 Avena  flavescens  is  a  very universal  plant,  but  more  especially in  fields  which  are  of  a  stony or  
 sandy nature;  its pale green foliage and yellow panicle  render it observable:  when young the panicle  
 is closed and drooping,  but afterwards it is  upright  and fully expanded,  assuming a riper yellow hue, 
 but finally changes to an unpleasant brown.----------Our British plants,  classed under the genus Avena, 
 are  not the  most profitable,  nor  are  they held in  much estimation by the grazier;  yet the flavescens  
 has  some  claim  to  our  favour,  and the  only one which we  could  not  spare  from  our pastures;  its  
 product  is  not  so large  as that o f  some  of its companions,  but it  affords  sufficient foliage  to render  
 it  useful,  and,  by being in perfection when the other grasses  are  usually cut for hay, we  receive the  
 full benefit of its herbage, which we by no means do of the whole number of those admitted as pasture  
 grasses;  and although Avena flavescens cannot certainly be received into the first ranks o f favour, yet  
 it  may be placed among those  o f an inferior or  secondary order.
