orange orchards of Florida, where it volunteers abundantly and makes a tremendous 

 growth after the heavy fertilization given the trees, large crops of a fair quality of hay- 

 are taken off in the fall. It also volunteers in different sections in cornfields, with 

 other fall hay crops, and usually forms an important ingredient of the fall crop of for- 

 age throughout the South. 



No. 8730 was collected at St. Petersburg, Fla., June 13, 1907. The sample was at 

 full maturity and was cut close to the ground. It grew in a favorable situation in a 

 cultivated field.

TRICHLORIS FASCICULATA Fourn. 



The distribution of Trichloris fasciculata is usually given as dry plains and mesas, but 

 in our experience it commonly inhabits rather favorable situations in the edges of 

 shallow washes, where it receives some benefit from irrigation. It is distributed from 

 Texas to Arizona and southward into Mexico. It sometimes produces a magnificent 

 growth in limited situations in the Salt River Valley of Arizona, where irrigation or 

 seepage water escapes to lands where it has obtained a foothold. In such situations 

 it impresses one as being a favorable grass for cultivation. Its seed habits, however, 

 are rather against it, although these are better than in a good many species of the Chlo- 

 ridese. When it gets sufficient moisture, as it often does under artificial conditions 

 in irrigated districts, it will produce two crops a year, one in spring and the other in 

 midsummer. Upon the open ranges of the Southwest at the present time very little 

 of it is seen except an occasional stray stalk 3 feet or more high growing in the pro- 

 tection of thorny shrubs. 



No. 8385 was collected near Encinal, Tex., August 12, 1906. The sample was col- 

 lected when the seed was fully ripe. A great deal of it shattered, but the straw, leaves, 

 and culms were perfectly green. Many of the root leaves, however, were dead and 

 dry and were included in the sample, which was cut 2 inches high. No. 9426 was 

 collected near Devils River, Tex., July 23, 1908. The specimen was overmature, 

 the seed having all fallen, but the remainder of the plant was green and succulent. 

 It was cut about 1 inch high.
