Sub-var. pseudololiacea, Hackel, 1. c. 151. F. pseudololiacea, Fries, 



8umm. Veg. Scand. 75 (1846', has been seen near South Hinksey on 



waste ground, &c., but it appears to be only a starved form. 



Var. loliacea is extremely abundant in the rich alluvial meadows of 

 the Thames, stretching at intervals from Eynsham to Shiplake, and 

 contributing largely to the hay crops. Mr. Tufnail agrees with me in 

 considering it to be an undoubted hybrid ; he says it has remained 

 constant under cultivation for the past ten years in dry gravelly soil. 

 Neither in its native habitat nor under cultivation does it perfect 

 seeds. Often a form is met having branching lower spikelets, giving 

 the plant the appearance of F. pratensis, but, like the typical F. loliacea, 

 proved, Mr. Tufnail tells me, infertile under cultivation. 



F. elatior occurs in all the bordering counties.
