by cattle as all the Bents are/ Mavor's Ayr. Berks, 1809 (but this 

 also included A. alba). 



A. vulgaris is another variable species, which is an extremely abundant 

 grass in dry sandy soil and forms an excellent turf. Its panicles are 

 of a charming purplish-brown tint, and a field of it lighted up by the 

 declining sun is a beautiful sight. The Boar's Hill Range, the sandy 

 commons of Bucklobury, Cold Ash, Snelsmore, Oare, Aldermaston, 

 Greenham, Crookham, Burghfield, Mortimer, Risely, Early, Woking- 

 ham, Sunninghill, Windsor Park, &c., offer it in profusion. In shady 

 places the panicles are often green. 



Var. ARiSTATA, Parnell, Gr. Scot. t. 13, has been seen at Burghfield, 

 Tilehurst, &c. It is the awned form, possibly a hybrid of A* canina, 

 with which I have seen it growing. Mr. F. Tufnail found it in a vivi- 

 parous condition on Mortimer Common. 



A. vulgaris is found in all the bordering counties.

Dr. Boswell Syme considered this to be only a form of A. vulgaris 

 caused by its growing in arable soil, and I do not think it to be a good 

 species.
