234 CULTIVATION OF PLANTS. 



in a separate state, are difficult to sow, on account of their 

 filaments causing them to adhere together. To counteract 

 this, they are mixed with a portion of newly slaked lime, in 

 order to separate them; but not in such quantity as to injure 

 the seed. They are then well rubbed in a sufficient quantity 

 of dry sand, after which they may be sown. 



This species varies considerably in size and appearance when growing in 

 different soils and situations. In our best soils the radical leaves are very long 

 and luxuriant when it is known by the name of green grass. This has by 

 botanists been made a distinct species, under the name of Poa viridis; but it 

 is probably nothing more than a variety [very true]. It is, indeed, as MUHLEN- 

 BERG terms it, "optimum pabulum" being decidedly the most valuable of all the 

 grasses known in our pastures. It has not been found necessary to cultivate 

 it by sowing the seed; for when the land is duly prepared by lime and manure, 

 it soon takes possession of the soil or, comes in, as the farmers term it and 

 supersedes the artificial grasso. In very poor land it deteriorates so much, 

 that it would scarcely be recognised as the same plant. Dr. Darlington's 

 flora Cestrica, p. 75. 



11. Rough Stalked Meadow Grass. 



Dr. DARLINGTON says this species bears a strong "resem- 

 blance to the preceding, when growing in open grounds but 

 is far superior in value. " In England it is held in high re- 

 pute, being considered as one of the superior pasture grasses, 

 forming a part of the richest meadows. It is nutritive, and 

 greatly relished by pasturing animals. It delights in moist 

 and sheltered spots; hence it is found naturally in moist mea- 

 dows, and the edges of wet ditches. In dry and exposed 

 grounds its produce is inconsiderable; and this circumstance 

 must determine, in certain cases, the expediency of cultivating 

 it. It is considered as one of the six best British grasses for 

 laying down either dry or watered meadows. 



12. Fertile Meadow Grass. 



This is a native of Germany, where it is esteemed as one of 

 the superior pasture grasses. It grows near rivers, in wet 

 situations, and on moist grounds. It is said to perfect its seeds 

 abundantly. Experiments are yet wanting, on the value and 

 uses of this species, as well as many others. 



13. Annual Meadow Grass. 



This species, Poa annua, has an annual root; continues to 

 flower throughout the spring, summer, and autumn, but rarely 

 attaining, even in the most fertile situations,a height of more than 

 ten or twelve inches, which is an objection, but overcome, how- 

 ever, in the estimation of English farmers, by its great produce,
