CHAETOCHLOA VERTICILLATA (L.) Scribn. 



Chaetochloa verticillata (foxtail) is a common, introduced weed in waste places and 

 cultivated fields in many parts of the United States. It often furnishes some grazing 

 and is sometimes included with hay. 



No. 8792 was collected near Fargo, N. Dak., August 8, 1907. The sample was in 

 late blossom and cut close to the surface of the ground.

 CHLORIS CUCULLATA Bisch. 



Chloris cucullata is distinctly a sandy-land perennial, extending from Texas north- 

 eastward. It is a valuable species, producing a large quantity of root leaves of good 

 forage value. 



No. 8401 wa3 collected near Green, Tex., August 14, 1906. The sample represents 

 the plant in a state of overmaturity, two-thirds of the seed having shattered, the culms 

 being nearly all dead. The root leaves, however, were all green. It was cut close 

 to the surface of the ground. Its percentage of moisture was 6.11. Other constituents 

 (on a water-free basis) were as follows: Ash, 12.37; ether extract, 1.89; crude fiber, 

 29.12; nitrogen-free extract, 45.77; protein, 10.85; pentosans, 23.81. 



CHLORIS ELEGANS H. B. K. 



Chloris elegans is an annual plant growing 1 or 2 feet high, depending upon the situa- 

 tion in which it develops. It is a grass of great importance throughout the Southwest, 

 oftentimes taking up spaces which were formerly occupied by perennials and making 

 considerable of a volunteer crop of good pasture or hay in neglected places and along 

 irrigated fields. It produces an abundance of fertile seed and is consequently easily 

 established whenever the season is sufficiently moist, often upon lands which were 

 formerly stocked with perennials that have been largely killed out by overstocking. 

 In some situations the six-weeks grama and an annual species of Aristida occupy such 

 areas. In other places this grass goes in. Quite frequently, in portions of the Sulphur 

 Spring Valley in Arizona, over limited areas in favorable situations, 1J tons of hay 

 to the acre of this grass may be cut. It adapts itself well to cultivation and were it not 

 for the awns upon the seeds it would be much more promising for domestication. Of 

 course, it does not cure up as well when drought strikes it as the perennial gramas 

 (PL V, fig. 2.) 



No. 8578 was collected at Green, Tex., September 24, 1906. The sample represents 

 a very rank growth of the species in early maturity. It was cut close to the ground.
