PANICUM JUMENTORUM—Guinea grass. 
Description.—This is a perennial grass, of strong, vigorous growth, a 
native of Africa, extensively cultivated throughout the tropics. Mr. 
Charles Mohr, of Mobile, who sent the specimens for analysis, says: 
Uses.—It is planted with us in the beginning of April; admits the first cutting dur- 
ing the last week of May; it makes very large bunches, and is to be cut before ex- 
tending to the height of about 18 inches. In that stage it is very sweet, tender, and 
easily cured as hay. In moderately fertilized land and favorable seasons it can be cut 
every five or six weeks, yielding, by its throwing out numerous stolons, increased 
crops until killed down by frost. The roots are easily protected during the winter by 
a good covering with ground, like the rattoons of sugar-cane, and allowing of a mani- 
fold division, afford the best means of propagation. These root-cuttings are set out 
in March or the beginning of April,
