internodes, and a long-peduncled, ample panicle; branches mostly in

Syn.—P. stolonifera, Muhl. Rough meadow grass. 
Culms and sheaths usually rather rough ; branches of the pyramidal 
diffuse panicle mostly in fives ; spikelets two to three-flowered; flowers 
lanceolate, acute, prominently nerved, a little hairy on the keel; ligule 
acute, long; root fibrous. Perennial; flowers in July. Culms 1 to 3 
feet high. Meadows, &c. Wisconsin and Ohio. Introduced from Europe. 
This species of Poa is but little inferior in many of its qualities to the 
Poa pratensis, which it much resembles. It requires a moist rich soil, 
and should only be cultivated in connection with other species of grass. 
It is not adapted to permanent pasture as it gradually dies out, probably 
from the exhaustion of its peculiar food from the soil. It is preferred 
by oxen, horses, and sheep, to many other grasses, being cropped close, 
while the others are suffered to grow.
