No. 61. Calamagrostis cinnoides (Mulil.) Spreug. Reed. Bent- grass. 



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

 swamps, ranging from New England southward to Tennessee. No attempts 

 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 thrive in the open it would make a most excellent bay-grass for 

 low meadows. 



No. 62. Calamagrostis hyperborea amerioana (Vasey) Kearn. Yellow-top. 



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

 west. It affords a large amount of excellent hay if cut iu proper season. A 

 good grass for cultivation in moist, sandy meadows. 



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



A rather slender, erect jierennial, with narrow leaves, 

 and a contracted, densely flowered, brownish panicle, 

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

 North America, ranging along our northern borders 

 from Newfoundland and Maine to the Pacific, being 

 most abundant in tbe Eocky Mouutain 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 Seribn. 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 qualities of an excellent hay or pasture grass. 



No. 65. Calamovilfa longifolia (Hook) Seribn. Sand- 

 grass. (Fig. 25.) 



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

 sands or sandy soil along the shores of the Great 

 Lakes and in 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 Avasli by swift currents or 

 As a sand binder for interior regions of the country

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

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

 cultural value, but rather curious iu appearance. The strong rootstocks are
