296 GRASSES OF BRITAIN. 



Triticum pinnatum (variety) hirsutum. 



Hairy Upright Wheat- Grass. 



Plate CXXXVII. 



This variety is the same as that described by Koch under the name 

 of Brachypodium pinnatum (variety) vulgare. It also appears to be 

 the Brachypodium pinnatum of Hooker, in which the spikelets are 

 stated to be hairy. 



It is distinguished from the five preceding in the glumes and flo- 

 rets being covered with hairs very similar to that observed in Triti- 

 cum sylvaticum, so much so that the two plants are often confounded. 

 The short awns of the florets, however, with the upright growth of 

 the raceme, will distinguish it from Triticum sylvaticum. 



Flowers early in July. 



Gathered in Yorkshire on chalky soil.
