spring an abundance of fine foliage; but, though once ce-

Hab. Meadows and pastures common. May. If. 



An early and very productive grass. It grows naturally in 

 a moist soil, and is hence best adapted to improve very 

 wet ground, that may be drained of superfluous moisture, 

 or to form or ameliorate meadows that have a moist bot- 

 tom, and are not apt to be burnt up in dry summers.

Hab. Wet meadows and marshy places. July, Aug. If. 



25. AGROSTIS. 



1. A. vulgaris, stem erect, 12-18 inches high ; stipula abrupt, 

 very short ; panicle purplish, spreading, with divaricated capil-

Hab. Meadows and pastures. July, Aug. If. 



Forms the turf of Murton Moor, and similar sheep-walks.

 scythe well, producing fine foliage, and resisting drought 

 better than most.
