Andropogon furcatus, Andropogon Virginicus, and Andropogon ma- 
crourus are other species of this genus, which have similar characters 
with the preceding. In the great prairie region of the West these form 
an important quantity of the native grasses. Although useful as a re- 
source for stock having a range over uncultivated fields or grounds, their 
place should, as early as possible, be filled with more valuable grasses.

among other sweet-scented grasses, was strewn before the church-doors

The culms grow from one to two feet high, with short lanceolate leaves, 
_and an open pyramidal panicle, from 2 to 5 inches long. The spikelets
