170 TRIANDRIA— DIGYNIA. Arundo. 



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 Jiowers, 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 ^ore^ 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. Calamagrosfis ; and thus some botanists, who trusted to 

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

 as in other instances, misled.

Root fibrous, as Scheuchzer likewise seems to imply j scarcely 

 creeping j 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 3 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 Jiowers also, Calyx-
