A Handbook of Nebraska Grasses. 85 
rootstocks which often form such a compact sod as to 
render if a nnisance in farming lands. It is a good sand- 
binder, but otherwise has no agricultural value. It 
thrives in alkali soils even when the ground is heavily 
crusted with alkali. Thruout the State. 
HCHINOCHLOA., 
»». Nchinochloa crus-galli.. Barnyard Grass. (Fig. 22.) 
This is a rank-growing annual weed well-known in rich, 
cultivated ground, particularly about dwellings. It is so 
thoroly dispersed thruout the State as sometimes to appear 
to be indigenous. The species presents several quite dis- 
tinct forms, each having its own peculiar qualities. One of 
these has been cultivated in several places and is valuable 
for green feed and silage, but is too coarse and succulent 
to make good hay. 
ELEUSINE. 
dG. Bleusine indica. Goose Grass. (Fig. 58.) 
A coarse tufted annual generally regarded as a weed. 
particularly in lawns and about dwellings. Introduced 
from Europe and not common. 
ELYMUS. 
Elymus canadensis. Wild Rye Grass. (Fig. 112.) 
A stout, smooth perennial which probably has some 
agricultural value altho it has not been very thoroly tested. 
It is very abundant on the prairie, low flats, and along the 
smaller streams thruout the State. When cut early it 
should form a good quality of hay, tho the frequent pres- 
ence of “ergot” might render its use for this purpose 
dangerous. 
58. Elymus condensatus. Giant Rye Grass. (Fig. 108.) 
A stout tufted perennial grass of central Nebraska com- 
mon in wet alkali soils and along streams. the banks of 
which are often protected from erosion by its. rootstocks. 
This grass should also be of service as a sand-binding grass 
along railroads, ete. When young it makes good hay and 
when allowed to stand it provides considerable winter 
forage on the range. 
59. Blumus glaucus. (Fig. 113.) 
In moist soil. Central Nebraska. 
60. Elymus macounii. Macoun’s Lyme Grass. (Fig. 113.) 
A perennial grass of northwestern Nebraska
