1292. Agrostis alba, L. Native. British type. Range 

 1-2. 



I. Cressbrook Dale ! Burbage Edge, in plantation ! 



III. Burton-on-Trent, Hams; Shirley, Linton. "Observing 

 the uncertainty of the characters, especially those derived 

 from the open or closed panicle, which are usually supposed 

 to distinguish A. alba from its allies, I, whilst at Calke, 

 collected a series of illustrative forms which are still in my 

 herbarium. Mr. Bagnall has kindly looked over these, and 

 he finds amongst them his A. nigra, which may, therefore, 

 take its place in this list. I cannot, however, say that I had 

 perceived it to be other that one of a series of forms which 

 show the common species of Agrostis to be much less sharply 

 and clearly defined in nature than in books." Purchas, J. B.
