Biennial. June. 



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

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

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

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

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

 pula short, obtuse. Paiiicle rather close j its stalks all com- 

 pressed, dilated upwards, rough-edged, Spikelefs 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 Siipa membranacea of Linnseus. The latter is 

 a true Fesiuca, scarcely diftering from this, indeed, except in 

 being larger, with longitudinally furrowed Jioiuer-stalhs. 1 be- 

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



8. F. glgantea. Tall Fescue-grass. 



Panicle drooping, twice compound, spreading. Florets from 

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

 pula abrupt, auricled, clasping the stem.
