No. 61. Calamagrostis cinnoides (Mulil.) Spreng. Reed Bentgra.ss. 



A stout, reed-like grass, 3 to 5 feet bigh, not infrequent in low, moist grounds and 

 swamps, ranging from New England southward to Tennessee. No attemi)t& 

 have been made to cultivate it, and little is known of its agricultural value. 

 Probably of some use for low woodlands where grasses are desired for pasturage, 

 and if it will thriv^e in the open it would make a most excellent hay-grass for 

 low meadows. 



No. 62. Calamagrostis hyperborea americana (Vasey) Kearu. Yellow-top. 



A very common grass in low meadows and shady river banks throughout the North- 

 west. It artords a large amount of excellent hay if cut in proper season. A 

 good grass for cultivation in moist, sandy meadows. 



No. 63. Calamagrostis neglecta(Ehrh.)Gaertn. Pony- 

 grass. 



A rather slender, erect i)erennial, with narrow leaves, 

 and a contracted, densely flowered, brownish panicle, 

 3 to 6 inches long. A native of Northern Eurojie and 

 North America, ranging along our northern borders 

 from Newfoundland and Maine to tlie Pacific, being 

 most abundant in the Rocky Mountain region. Under 

 experimental cultivation it has succeeded well. It is 

 a productive grass, much liked by stock, especially 

 horses, and is deserving a place among the cultivated 

 species. 



No. 64. Calamagrostis suksdorfii Scribn. Pine-grass. 



A rather slender, erect grass, 2 to 3 feet high, with 

 smooth stems, narrow leaves, and contracted, usually 

 pale, straw-colored panicles. A common grass in the 

 Northwest, growing in low pine woods or on moist 

 mountain slopes. It is said to be one of the most 

 common grasses in Washington, and it presents all 

 the ([ualities of an excellent hay or pasture grass. 



No. 65. Calamovilfa lougifolia (Hook) Scribn. Sand- 

 grass. (Fig. 2.5.) 

 A stout, long-leafed grass, 1 to 4 feet high, growing in 

 sands or sandy soil along the siiorcs of the (ireat 

 Lakes and iu the Missouri region of the West, ex- 

 tending southward to Kansas. Its very strong and 

 far-reaching rhizomes or creeping "roots" make this 

 an exceedingly valuable grass for binding drifting 

 sands, or those subject to wash by swift currents or 

 the beating of the waves. As a sand binder for interior regions of the country 

 this grass is probably unsurpassed. Its bmg, tough leaves suggest a possible 

 vahn- for jtajier making. 



No. 66. Campulosus aromaticus (Walt.) Sdribn. Toothache-grass. (Fig. 2t!. ) 



A perennial grass with erect stems 3 to 4 feet high. Native of the Southern States 

 from Virginia southward, growing in the wet pine barrens, possessing no agri- 

 cultural value, liut rather cnrinus in ajtpearance. The strong rootstocks are 

 leuion-scented and have a pungent taste. 



No. 67. Ceuclirus echinatus Linn. Cock-spur. 



A rather stout annual, with branching culms 1 to 2 feet long, and dense heads or 

 spikes made n\> of 20 or more globul.ir, spiny burs containing the sj)ikel<'ts. It 

 is a weed of the fields and waste places of the Southern and .Southwestern States.
