In mountainous woods of Scotland, Ireland, and the north-west 

 part of England. 



Root fibrous, tufted. Stems several, upright, 2 or 3 feet high, leafy, 

 round, smooth 5 sheathed at the bottom with many short, blunt- 

 pointed, polished scales. Leaves lanceolate, or linear, flat, taper- 

 pointed, erect, striated, many-ribbed, rough at the edges, and 

 sometimes on both sides 3 their length from 6 to 18 inches 3 

 their colour a deep green. Sheaths cylindrical, striated, roughish 

 upwards 3 those of the upper leaves very long. Stipula short, 

 jagged 3 the uppermost a little pointed. Panicle spreading 

 while in flower, afterwards close 3 the branches slender, angu- 

 lar, smooth except the ultimate ones. Spikelets small in compa- 

 rison with the herbage, erect, often tinged with purple or brown. 

 Cal. of one awl-shaped, and one linear valve, both pointed, but 

 rather membranous than awned at the tip. Outer valve of the 

 corolla lanceolate, but inflexed at the edges, roughish upwards, 

 keeled, with a remote rib at each side, the point elongated, 

 membranous, with scarcely any traces of an awn, though some- 

 times strongly keeled to the tip of the membrane, and in /3 

 slightly awned occasionally 5 inner valve cloven, its 2 ribs 

 smooth, and brought so nearly together by a central fold of the 

 membrane, as often to assume the appearance of a simple keel 3 

 in /3 they are sometimes rough, Nect. cloven. Germen oval. 

 Styles very short. Stigmas cylindrical, feathery, small. 



/3 is a smaller plant, with much narrower leaves, and scarcely more 

 than 2 perfect florets, the upper ones falling off early, for want 

 of strength. I am entirely obliged to my friend Prof. Hooker, 

 for suggesting it to be a variety only, differing from the original 

 species as F. triflora does from gigantea. 



10. F. loliacea. Spiked Fescue-grass, 



Spike two-ranked, drooping. Spikelets nearly sessile, linear- 

 oblong. Florets cylindrical, awnless, pointed, with five 

 slight ribs at the top.
