Eatonia nitida. (See Short-leafed Eatonia.) 
Eatonia pennsylvanica. 
This ie flourishes in moist meadows and open woods, but forms too small a part 
of the forage to be of much importance for either pasturage or hay. Like early 
ses grass, however, the forage is of excellent quality. i

False Buffalo-grass ( Munroa squarrosa). 
A low-growing grass of dry, sandy soils. Stock seldom eat it on account of its harsh 
stems and rigid, pointed leaves. It is said that the agricultural ants collect the 
seeds of this grass for their store of winter food. 
False Redtop. (See Poa flava and Panicum virgatum.) 
Feather Bunch-grass (Stipa viridula). 
Very abundant in dry, sandy soils, furnishing a large amount of forage. The spears" 
of this grass are not so injurious as are those of the other two species of Stipa 
occurring in the Dakotas. 
Festuca elatior. (See Tall Fescue.) 
Festuca elatior pratensis. (See Meadow Fescue.) 
Festuca octoflora. (See Slender Fescue.) 
Festuca ovina. (See Sheep's Fescue.) 
Fine-topped Salt-grass (Sporobolus asperifolius). 
More or less abundant in saline soils in the western part of the Dakotas. Cattle 
are not very fond of it, but will eat it when other forage is scarce, and as it 
thrives on soils that will grow but few other grasses it may be valuable in 
some localities. 
Floating Meadow Foxtail. (See Wild Water Foxtail.) 
Fowl Meadow-grass (Poa flava.) 
This is one of the most valuable of the native species of Poa. It occurs in both dry á 
and moist soils, but reaches its best development in the latter. In many locali- 
ties in the eastern part of both States it non a 3 portion of the forage. 
It is particularly valuable on lowland dow overflowed. 
E In the Sioux Valley at Brookings, S. Dak., this prer sometimes furnishes 50 per 
E cent of the hay cut from the meadows near the riv 
Glyceria airoides. 
Grows in old lake beds and in sandy alkaline basins. It is most abundant in the 
Bad Lands. In the latter region it often furnishes considerable forage. 
Glyceria aquatica. (See Reed Meadow-grass.)
