ERAGROSTIS LUGENS Nees. 



Eragrostis lugens is a tall, hard, perennial species, strictly a filler only and of 

 secondary quality. It occurs mostly on rocky, exposed situations and produces feed 

 that remains green quite late in the season. It is not eaten until other more palatable 

 feed has been used. i 



No. 7091 (E. O. W.) was collected in the San Andreas Mountains near Las Cruces, 

 N. Mex., October 6, 1912. Its percentage of moisture was 5.79. Other constituents 

 (on a water-free basis) were as follows: Ash, 9.03; ether extract, 1.77; crude fiber, 

 32.58; nitrogen-free extract, 49.82; protein, 6.80; pentosans, 25.46. 



ERAGROSTIS SECUNDIFLORA Presl. 



Eragrostis secundiflora is distinctively a sand-grass, being characteristic of dry, 

 sandy areas from Florida to the Pacific coast. While extensively grazed, it is not of 

 first quality, either in abundance or palatability. It is wiry in its nature and rejected 

 by live stock until more palatable feeds fail. 



No. 8390 was collected at Encinal, Tex., August 12, 1906. The sample was a little 

 underripe, but contained considerable old dead leaves, although nothing was included 

 but this year's growth. It was cut off about half an inch above the ground. Its per- 

 centage of moisture was 5.87. Other constituents (on a water-free basis) were as 

 follows: Ash, 15.15; ether extract, 2.12; crude fiber, 30.39; nitrogen-free extract, 

 45.70; protein, 6.64; pentosans, 23.96. 



ERAGROSTIS SPICATA Vasey. 



Eragrostis spicata is a tall, conspicuous grass, not abundant enough in the United 

 States to be seriously considered as a native forage. It is a hard, rank species, not 

 particularly relished by stock, although grazed in close pastures. 



No. 8402 was collected at Green, Tex., August 14, 1906. The seed was ripe, but not 

 fallen, and all herbage was green and fresh. It was cut 4 inches high.' Its percentage 

 of moisture was 10.30. Other constituents (on a water-free basis) were as follows: 

 Ash, 8.77; ether extract, 1.20; crude fiber, 36.31; nitrogen-free extract, 47.44; pro- 

 tein, 6.28; pentosans, 23.28. 



ERIOCOMA CUSPEDATA Nutt. i 



Eriocoma cuspidata (Indian millet) is a grass peculiarly adapted to the loose, 

 sandy soils of the arid West. Although not particularly confined to such situations, 

 it is here that it reaches its most striking development. It is distinctively a brnch 

 grass, growing scatteringly and often in very large bunches in the most sterile of soils, 

 often upon unstable sands. It is a highly prized and valuable species, the only 

 objection to it being that it does not grow abundantly enough. Nowhere is it found 

 forming anything like a ground cover. Sometimes in the edges of cultivated fields, 

 upon railroad embankments, beside roadways, and in other situations where the 

 ground is loosened up, its growth is very much facilitated. It is not a grass that 

 bears grazing very well, being easily pulled up by the roots or tramped out by stock. 



No. 8340 was collected near Ashfork, Ariz., May 30, 1906. This sample represents 

 the plant in early maturity. This is true, however, of not over half of the plants,
