Woods, Aldermaston, and Padwoi*th Woods, at Cothill, Easthampstead, 

 and in Windsor Forest (teste Prof. Hackel). 



A luxuriant form with more numerous florets is the var. MutTirLORA, 

 Eeichb. Ic. Fl. Germ, et Helv. i. t. 162, f. 420. 



This and the last-named species may be readily distinguished by 

 observing the ligule. In this species it is long and acute, in P. pratensis 

 short and blunt. 



P. trivialis is found abundantly in all the bordering counties.

Mr. S. Ruclge. 1800, in Herb. Brit. Mus. The latter of the aggregate 



species. 



Mr. Stillingfleet, in Misc. Tracts, ed. 3, 1775, informs us that Mr. Dean, 



a very sensible farmer at Ruscombe, in Berkshire, assured him 



that a ' field always lying under water of about four acres was 



covered with a kind of grass that maintained five farm horses in 



good heart from April to the end of harvest. . . .' This proved to be 



the flote fescue [Festuca fluitans'], with a mixture of marsh bent, Curtis,

 plants. 



When P. fluitans is reduced to a single spike, and has narrower and
