In the feveral catalogues of plants publifhed by me at different periods, I have long fince given to this very 
diftin& fpecies of Agroftis the name of /étacea, or Sbeep's fefcue-leaved, the foliage being much finer than that of 
any other of our Britifh fpecies, and confiderably refembling that of the Sheep's Felcue graís; regarding this 
name as more expreffive than that of a/pzza, which was perhaps previoufly given it by Scorori, I am not 
inclined to alter it, more efpecially as Gwxriw has alfo an a/pina, which, if we pay any regard to his figure 
of reference, is not our plant. | 
The firft information I received of this grafs was from my Gardener, Rosert Squiss, who fent me up 
fome tufts of it from Piddletown-Heath, Devonfhire, where his relations lived; I have fince found it to be one 
of the moft common plants of that county, and Cornwall, there being fcarcely a heath in either on which it 
does not abound ; I have found it alfo plentifully on Bagfhot-Heath, but not in the neighbourhood of London; 
Lord Gainssporoucu obferved it near Lymington, Hampfhire. 
It flowers in July and ripens its feeds in Auguft. me ee a 
Readily as it grows in its wild ftate, I have not been able to keep it alive in my garden without planting it 
in bog earth, and beflowing unufual care on 1t. | : me "s. 
The peculiarity of its place of growth, the finenefs of its glaucous leaves, the clofenefs of its panicle, the 
length of its arifte, fo clofely embraced is one of the valves of the calyx as to appear at firft as if proceeding 
from it, which we have never obferved to be wanting, joined to other chafaéters noticed in the defcription, 
fufficiently point it out to the moft common obferver. : 
As am agricultural plant, it does not appear to have much to recommend it; where it abounds, it muft 
conftitute much of the fheep feed. ;
