CRESTED DOGSTAIL. 



1.2. Select those shoots in whose bases a 

 characteristic yellow colouring matter is 

 developed. 



As in red sheathed grasses so here the blade is 

 strongly ribbed on the upper, and shining on the 

 lower surface, but the base is never eared. 



xiv. 12. The sheath is not quite so flat as that of perennial 

 ryegrass ; this is connected with the circumstance 

 that the blades contained in the sheath are less 

 closely folded, and thicker. Extra thickness makes 

 the blade feel harder between the fingers. 



xiv. ii. The ligule has a minute character, quite unique 

 among grasses ; the short collar-like structure is 

 peaked, opposite the blade, into a pair of ear- 

 like processes. This form of ligule is described as 

 eared. In sheep's fescue, the ligule, though eared, 

 is very different. 

 Summary : 



a. Sheath yellow coloured and somewhat flat 



b. Ligule eared. 



MEADOW FOXTAIL. 



i- s Select those shoots whose bases are dark, 

 almost black, in colour. 



.Meadow foxtail, to which these shoots belong, is 

 one of the large grasses of our pastures. It is to be 

 found on heavy soils. 



The black parts are old withered sheaths. On 

 removing these, the young sheaths are laid bare, and 

 the very distinctive violet colouring matter, which 

 these contain, is readily noticed.
