194 IIORTUS GRAMINEUS M'OBURNENSIS. 



the second and last week of July, according to the state of the 

 weather. 



POA glauca. Glaucous Meadow-grass. 



Specific character- : Panicle spreading, spikelets ovate ; florets 

 from two to five, obscurely five-ribbed, bluntish, silky at 

 the keel and lateral ribs, hairy at the base, without a web ; 

 stipulas of the lower leaves very short and blunt. Sm. Engl. 

 Fl.i. p. 128. 



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

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

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

 pina, Poasubcarulea, and Poapratensis,&ud 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. 



Experiments. At the time of flowering, the produce from a 

 rich black sandy loam is

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

 Scotland. It inhabits alpine situations, but is easily propagated, 

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

 every kind of soil. It grows to a larger size than the 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 to a great number 

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