 4 to 8 inches long; ligule obtuse, 1 to 2 lines long.

 bearing beyond the middle or nearly to the base.

Oregon and Washington, in the mountains. This species is rather variable and 

 difficult to define, like some others of the same genus in this region. Its stoloniferous? 

 perennial habit and abundant foliage indicate that it might be valuable for pasturage
