HORTUS GRAMINEUS WOBURNENSIS. I'il 



might be presumed from the plentiful manner in which it is 

 produced ; nor does the plant attain to maturity so soon as 

 many other grasses that have equal merits in other respects. 

 The above facts do not offer sufficient ground to recommend 

 the nerved meadow-grass strongly, for the purposes of the 

 agriculturist ; nor go the full length to discourage further 

 attempts to cultivate it to more advantage, as it is a foreign 

 plant, and its defects may probably be lessened by fre- 

 quently raising it from seed ripened in this climate. 



Farther experience in the cultivation of this grass enables 

 me to state, that it possesses very valuable properties, and 

 that it will be found a valuable ingredient in permanent 

 pastures, where the soil is not too dry, but of a medium qua- 

 lity as to moisture and dryness. 



It flowers in the third week of June, and the seed is ripe 

 in the last week of July. 



POA glauca aesia. Sea-green Meadow-grass. 



Specific character : 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. 



Obs. — Culms from six inches to a foot and a half, accord- 

 ing to the nature of the soil it grows in. The leaves 

 are bluntish, flat and smooth on the back next 

 the base, but in other parts rugged ; sheaths the 

 length of the leaves, striated, somewhat rupged. It 

 seems to be very different from the poa glauca in the 

 Flora Danica 5 that approaches nearer to the poa iie- 

 moralis. Whole plant of a deep glaucous colour. Na- 

 tive of Scotland. Root fibrous. Perennial. 



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

 a brown loam is 6,806 lbs. per acre. 



At the time the seed is ripe, the produce is 4,764 lbs. 

 per acre. 



The weight of grass at the time the seed is ripe is less 

 than that at the time of flowering; which at first sight 

 appears contrary to what might have been expected, as the
