\U TRIANDRIA— DIGYNIA. Festuca. 



Nearly akin to the last, with which every part of the fructification 

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

 clothed with leaves to the top j 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.

 awned. One valve of the calyx very short.

Biennial. June. 



Root fibrous, slightly downy. Stems several, from 6 to 14 inches 

 high, erect, leafy nearly to the top, simple, very smooth. Leaves 

 acute, somewhat involute j very smooth at the back ; furrowed, 

 and often hairy, on the upper side. Sheaths longer than the 

 leaves, ribbed, smooth j the uppermost large and inflated. Sti- 

 pula short, obtuse. Panicle rather close 5 its stalks all com- 

 pressed, dilated upwards, rough -edged. Spikelets erect, or a 

 little turned to one side. Florets keeled, not cylindrical. Awns 

 long, rough, often purplish. One valve of the calyx is so minute 

 as to be scarcely discernible, by which character this species is 

 readily known from all our other grasses, though it agrees in 

 that respect with Stipa membranacea of Linnaeus. The latter is 

 a true Festuca, scarcely differing from this, indeed, except in 

 being larger, with longitudinally furrowed jlower- stalks. I be- 

 lieve it to be only a more luxuriant state of the same plant. 



8. F. gigantea. Tall Fescue-grass. 



Panicle drooping, twice compound, spreading. Florets from 

 three to six, ovate-lanceolate, shorter than their awns. 

 Stipnla abrupt, auricled, clasping the stem.
