170 TRIANDRIA— DIGYNIA. Aruudo. 



branched at the bottom. Leaves linear-lanceolate, with a sharp 

 taper point, roughish ; a little glaucous underneath. Sheaths 

 striated, scarcely rough, except the long upper one. Stipula lan- 

 ceolate, acute, thin, soon torn. Panicle smaller, closer, more 

 erect, and of a brighter purplish hue than in the last ; the 

 branches rough, spreading when in flower only, beset with nu- 

 merous, crowded flowers, directed to one side. Calyx-valves 

 nearly equal, rough at the keel. Outer valve of the corolla about 

 half as long as the calyx, membranous, flat, with 2 rough mar- 

 ginal ribs at each side, and cloven at the point ; bearing from 

 its back, about the middle, a twisting inflexed awn, which rises 

 as high as the points of the calyx ; inner valve much smaller, 

 slightly cloven. The soft hairs, originating from the base of each 

 valve of the corolla, nearly surround the whole floret, and are 

 about as long as the calyx, or finally somewhat longer, when 

 they carry away the ripe seed. 

 Linnaeus by mistake interchanged Scheuchzer's synonyms of this 

 and A. Culamagrostis ; and thus some botanists, who trusted to 

 his citations, rather than to his definitions and characters, were, 

 as in other instances, misled.

Near Oundle, Leicestershire ; Mr. Scampton. Dillenius. In the 

 fenny parts of Norfolk, Cambridgeshire, and Lincolnshire, not 

 unfrequent. 



Perennial. June, July. 



Root fibrous, as Scheuchzer likewise seems to imply; scarcely 

 creeping ; the fibres woolly. Whole plant much more slender 

 and delicate than the last. Stems 3 or 4 feet high, very smooth. 

 Leaves narrow, pointed, bright green ; roughish beneath; some- 

 times a little hairy on the upper side. Sheaths smooth. Stipula 

 oblong, obtuse, decurrent, mostly torn. Panicle much branched, 

 loosely spreading everyway, as are the flowers also. Calyx-
