Fig. 255. CYNOSURXJS CRISTATUS L. Sp. PI. 72. 1753. DOG'S-TAIL GRASS.- 

 A slender, erect perennial 3-7.5 dm. (10-21°) high, with narrow leaves and 

 rather slender, erect, spike-like panicles 5-10 cm. (2'-4') long. Sheaths shorter 

 than the internodes; ligule 1 mm. (i") long, truncate; leaf-blades 2-13 em. 

 (l'-5') long, 1-4 mm. {i"-2") wide, glabrous. Spikelets arranged in clusters, 

 the terminal ones {a,b) fertile, the lower ones (e) larger and sterile; glumes of 

 the former about 3 mm. (H") long, pointedor short awned, those of the sterile 

 spikelets very narrow, strongly scabrous on the keel.— Sparingly established in 

 fields and waysides, Newfoundland to Ontario, south to New Jersey; Portland, 

 Oregon. (Europe.) June to August. 



This species is valuable for lawns, forming a close, compact sod, and thrives 

 in shaded places. As it has a high nutritive value it is recommended for mix- 

 tures used for permanent pastures. The mature stems of this grass are among 

 the most valuable of those used in the manufacture of Leghorn hats.
