146 TRIANDRIA— DIGYNPA. Festuca. 



r purplish, covered with the unchanged corolla, but I believe 

 not combined with either glume. 

 |S is a much more delicate, paler, and narrower-leaved grass, 

 about 2 feet high, with a smaller, more upright, panicle; the 

 outer valve of the calyx sometimes a mere bristle. But though 

 reckoned distinct by Lin mens and Scheuchzer, it proves, when 

 carefully examined,' to be marked by no real specific character, 

 the number o\'jlorets being undoubtedly variable.

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 j 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 ; their length from 6 to 18 inches ; 

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

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

 jagged j the uppermost a little pointed. Panicle spreading 

 while in flower, afterwards close j 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 ; inner valve cloven, its 2 ribs 

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