common, particularly where the land is periodically overflown. 

 In a piece of meadow ground on the banks of the river Trent, 

 near Nottingham, I found this grass to constitute the principal 

 herbage. 



It flowers in the last week of June, and ripens the seed (if any) 

 in the third week of July. 



FESTUCA glabra, var. Smooth Fescue. 



Specific character: Panicle branched, upright, compact ; spike- 

 lets spear-shaped, 4-6-flowered, smooth, awned. Root 

 fibrous. — Fig.l. Calyx magnified. 2. Floret magnified. 



Obs. — This is nearly allied to the Festuca duriuscula and 

 Festnca rubra ; it differs in having the awns longer, panicle 

 branches and spikelets smoother; spikelets shining, root 

 scarcely creeping, root-leaves much longer. This is, ac- 

 cording to Sir James Edward Smith, a variety of the Festuca 

 rubra. To the Agriculturist the distinction, creeping root, 

 is sufficient to guide him in this instance, as the varieties of 

 the creeping-rooted species are all to be rejected as less 

 desirable for cultivation ; and among the fibrous-rooted 

 varieties of the Festuca duriuscula, there is not so great a 

 difference in their comparative value, as to render the adop- 

 tion of one for the other of so much importance as in many 

 other instances, where the distinctions are equally minute.
