POA ORCUTTIANA Vasey. 



Poa orcuttiana is a species which is characteristic of the western slope of the southern 

 Sierras. It is a highly prized, important pasture grass. Like some of the other species 

 of the P. bucldeyana group, it grows in large bunches. At the present time the weedy 

 bromes and fescues are the most conspicuous grasses in the upper foothills, where this 

 species grows, and are much less palatable to live stock. This grass is, therefore, 

 closely cropped upon all the pasture lands of the section. In the localities where the 

 specimen cited below was secured, it grew in almost pure stands on steep, bare, 

 northern slopes of the mountains. 



No. 9103 was collected at Cali en te, Cal., March 24, 1908. The sample was in very early 

 blossom and was cut as close to the ground as practicable. Its percentage of moisture 

 was 1.65. Other constituents (on a water-free basis) were as follows: Ash, 7.96; 

 ether extract, 3.21; crude fiber, 31.72; nitrogen-free extract, 48.02; protein, 9.09; 

 pentosans, 24.29. 



POA SCABRELLA Benth. 



Poa scabrella is a palatable species of bluegrass, but strictly of secondary importance, 

 because it never occurs abundantly. It is found in open gravelly ground and also in 

 partial shade of timber throughout the Pacific States from Oregon southward. It was 

 doubtless formerly of much more importance before the native plants were replaced by 

 the introduced annuals now everywhere dominant in the region. 



No. 7116 (E. O. W.) was collected at Moorpark, Cal., April 18, 1913. The specimen 

 was just coming into flower. Its percentage of moisture was 6.59. Other constituents 

 (on a water-free basis) were as follows: Ash, 5.30; ether extract. 2.24; crude fiber, 

 35.22; nitrogen-free extract, 50.68; protein, 6.56; pentosans, 26.50. 



POLYPOGON MONSPELIENSIS (L.) Desf. 



Polypogon monspeliensis is a foreign, annual, short-bearded grass, widely introduced 

 in this country from Maine to California. It is especially abundant in moist alluvial 

 soils of the Great Basin and California regions. Its best growth is attained in the 

 edges of fresh -water ponds and streams where the warm waters are but 2 or 3 inches 

 in depth. In such small areas it often forms a pure growth and attains a height of 12 

 to 24 inches. It is readily eaten in the green c^Mdition by stock. 



No. 8879 was collected near The Dalles, Oreg., August 22, 1907. The sample waa 

 completely dried up and was cut close to the ground.
