TRIANDRIA— DIGYNIA. Festuca. J 43 



ck' of a few long-stalked s-pikclets, turned most to one side. 

 Outer valve of the cali/x extremely narrow, aeute ; inner .3-ribbed, 

 awned. Florets slender, cylindrical, each with a tajjeriny; rough 

 point, and a long uj)right awn ; inner valve very thin and pellu- 

 cid, roughish at the edges near the summit only, the green la- 

 teral ribs smooth. Geriiien elliptic-oblong. Slij'ics scarcely anv. 

 Stigmas feathery, minute. Seed oblong, deeply channelled above, 

 convex beneath, downy at the point, quite unconnected with 

 the glumes, which remain unaltered. Schrader describes the 

 flowers of this and the following with only one siaincn, which 

 we have not observed in England. Mr. Sowerby has drawn 3 

 in the present species^ as has Leers in the next. 



6. F. Myurus. Wall Fescue-grass. 



Panicle drooping, elongated, rather close. Florets taper- 

 ing, shorter than their awns, rongh at the top. Leaves

On walls, and barren sandy ground, frequent. 



Annual ; according to Schrader biennial. June, July. 



Nearly akin to the la^t, with which every part of tlie fructification 

 agrees ; but the whole plant is larger and stouter ; the stem 

 clothed with leaves to the top ; and the panicle four times as 

 long, rendering the plant very conspicuous when waving in the 

 wind on the ridge of some ruined wall. It is perhaps " the 

 trembling rye-grass " of poets. 



Scheuchzer's figure represents a variety with more downy or hairy 

 spikelets than I have ever seen, though they are sometimes rough 

 with minute points, nearly all over. 



7. F. uiiigltimis. Single-husked Fescue-grass. 



Panicle erect, nearly simple. Florets ta})ering, compressed, 

 awned. One valve of the calyx very short.
