Obs. — This species resembles the Poa nemoralis, and, in a less 

 degree, the P. trivialis, and likewise affects a similar soil ; 

 while the preceding variety of it resembles more the Poa al- 

 pina, Poa subcarnka, and Poa pratensis, and like these, affects 

 a somewhat drier soil. Culms from a foot and a half to two 

 feet in height. Whole plant of a light pale glaucous colour. 



Native of Britain. Root fibrous. Perennial.

rich black sandy loam is —

This grass is said to be a native of the north of Englar^, and 

 Scotland. It inhabits alpine situations, but is easily pro.jagated, 

 as it perfects plenty of sefed, which vegetates freely on almost 

 every kind of soil. It grows to a larger size than t?ie sea-green 

 meadow-grass ; and if the above details of its produce and nutri- 

 tive powers be compared with those of that grass, it will be found 

 greatly superior. But it is still much inferior t:) a great number 

 of grasses, in the quantity of herbage, hay, and nutritive matter
