ROUGH-STALKED MEADOW-GKASS. 449 



admissible in dry light soils, where others are liable to suffer 

 from drought. 



It is one of the plants recommended to be sown for perma- 

 nent pasture in light soils, for warrens or light sandy downs, 

 and for dry gravelly situations which resist a sward from all 

 other means, in the proportion of from 1 Ib. to 4 Ib. of the 

 seeds per imperial acre. A bushel of the seeds has an average 

 weight of 13 J Ib., and the number of seeds in an ounce 

 amounts to 243,000. 



Poa trivialis. The rough-stalked or stoloniferous meadow- 

 grass is named by botanists Poa trivialis. It is a creeping- 

 stemmed perennial. It grows from 12 to 18 inches high. 

 It flowers in the third week of June, and its seeds ripen in 

 the middle of July. It grows naturally in moist pastures, 

 meadows, waste grounds, shady places. It is not culti- 

 vated profitably in dry, exposed situations. It is, however, a 

 highly nutritious and useful grass, which should have a place 

 generally in permanent pastures, and is especially suited, along 

 with Agrostis stolonifera, the marsh creeping bent-grass, and 

 Glyceria fluitans (Poa fluitans), the floating sweet-grass, for 

 irrigated meadows. 



It is one of the plants recommended to be sown for perma- 

 nent pasture in medium and heavy soils, for permanent lawn- 

 pastures, for fine lawns, bowling-greens, &c., kept constantly 

 under the scythe, in lands in preparation for irrigation, for 

 permanent pasture and hay in orchards and other grounds 

 much overshadowed by trees, for pasturage and cover in thick 

 shady woods, for improved deep mossy ground intended to be 

 kept in grass, for marshy grounds and such as are occasionally 

 overflowed by fresh-water tides. A bushel of the seeds has an 

 average weight of 15J Ib., and the number of seeds in an ounce 

 rises to 217,000. 



Poa annua, annual meadow-grass, is one of the commonest
