STIPA EMINENS Cav. 



Stipa eminens (needle grass) is one of the original valuable perennials of California, 

 which is found as far east as Texas and south into Mexico. It is a valuable, palatable 

 species, but has been so much reduced in quantity by close grazing that it is now of 

 very secondary importance. It occurs commonly as a filler in rocky, broken country, 

 and is of some use as a spring feed. 



No. 7069 (E. O. W.) was collected upon limestone hills in the foothills of the San 

 Andreas Mountains, near Las Cruces, N. Mex., September 8, 1912. Its percentage of 

 moisture was 4.82. Other constituents (on a water-free basis) were as follows: Ash. 

 6.53; ether extract, 2.37; crude fiber, 38.57; nitrogen-free extract, 45.38; protein, 7.15; 

 pentosans, 28.19. 



STIPA RICHARDSONII Link. 



Although it always grows scatteringly upon dry hillsides and in open pine timber, 

 Stipa richardsonii furnishes many a relished morsel of feed to cattle throughout the 

 region in which it thrives. It always grows in scattering large bunches and is 

 invariably closely grazed. 



No. 8878 was collected at Columbia Falls, Mont.', August 17, 1907. The sample was 

 mature and was cut close to the ground. Its percentage of moisture was 6.06. Other 

 constituents (on a water-free basis) were as follows: Ash, 6.45; ether extract, 2.07; 

 crude fiber, 35.88; nitrogen-free extract, 50.54; protein, 5.06; pentosans, 28.37. 



STIPA SETIGERA Presl. 



Stipa setigera is decidedly conspicuous in southern California, growing like many 

 of the other species of the genus in large, tall, spreading bunches often 3 feet in height. 

 It appears to make a very fair quality of pasturage, but is never abundant enough to 

 give a distinctive character to the forage outside of very circumscribed areas, and 

 nowhere does it form a complete stand. 



No. 7040 (E. O. W.) was collected near San Luis Obispo, Cal., April, 1912. No. 

 8288 was collected near Banning, Cal., May 14, 1906. This sample was nearly mature 

 and was cut about 2 inches high.
