1Q2 HORTUS GR,AMJ.NEUS WOBURNENSIS. 



:, severe, and the summers warmer than in |his climatf^ ; and the 

 plants, natives of Siberia, exhibit a similar habit, for the severer 

 the winter, the greater is their produce ; and the milder the 

 winter, their produce is comparatively less. The long-rooted 

 clover is one of this class: after a severe winter the produce 

 is very great, but after a mild winter the produce is considerably 

 inferior. 



The nerved meadow-grass affects most soils, but not such 

 as are tenacious. The seed does not vegetate so readily as 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 grounds 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 mor^ advantage, as it is a foreign plant, and its defects may 

 probably be lessened by frequently 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 quality 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 casia. Sea-green Meadow-grass. 



Specific character: Spikelets ovate. Florets from two to five, 

 obscurely five-iibbed, 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. 

 Ohs. — Culms from six inches to a foot and a half, according 

 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 

 rugged. It seems to be very different from the Poa glauca 

 in the Flora Danica ; that approaches nearer to the Foa 

 nemoralis. (Sir James Edward Smith.) E. Bot. 1719. 

 Whole plant of a deep glaucous colour. 

 . JN^ative of Scotland. Root fibrous.. . Perennial.
