Elymus innovatus Beal. Wild Rye. 
A common grass of dry upland woods and prairies. It is the primary 
herbaceous species in the scant ground cover of the vast tracts of upland 
aspen woods, and as such is one of the most important sources of forage 
in the summer feeding grounds of the buffalo. It does not make a thick 
turf, but its long slender leaves and culms appear rather early in the season, 
before the semi-open prairies have, had time to produce much new green 
material, so that it helps to tide the herds over the difficult spring feeding 
period. Young spikelets are produced during the last week in June, and 
the plants are in full flower during July. Fruit is matured in the latter 
half of August.

E. Macounii Yasey. 
Known in the park area only from the following specimen.

Hordeum Juba turn L. Squirrel-tail Grass. 
t A common grass of prairie slough margins and cabin clearings. It 
becomes abundant on the edges of shallow salt flat depressions in the Salt 
Plains, where broad bands of it are made especially noticeable by its wav- 
ing, plume-like heads. In the early stages of growth it furnishes con- 
siderable forage, but when the fruits begin to mature the long barbed awns 
become embedded in the tender flesh about the mouths and noses of grazing 
stock and often cause sores. Young inflorescences are produced early in 
July, and fruit in late July or August.
