HORTUS GKAMINEU.S WOU U RN ENSIS. 187 



avvned, awn longer than the valve, protruding from the 

 back, fixed a little below the middle. 

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

 a sandy soil, incumbent on clay, is 6,125 lbs. per acre. 

 The produce of latter-math is 2,041 lbs. per acre. 

 On comparing the properties of this grass with those of 

 the common bent (agrosfis vulgaris), it will be found inferior 

 in the proportion nearly of 5 to 3. It appears to be a very 

 scarce grass : I have only seen it twice in a wild state, and 

 then but in very small quantities. It grows on the east 

 side of Aspley Wood, and by the side of a field near Wa- 

 vendon. 



It flowers about the second week of August, and ripens 

 the seed about the beginning of September. 



AGROSTIS caninaj'ascicularis. Bundle-leaved Bent, Tufted 

 Bent. 



Variety with the leaves in dense bundles, and culms 

 striking root at the joints. 



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

 a sandy soil is 2,722 lbs. per acre. 



In old pastures, on light soils, this bent may be readily 

 distinguished in the autumn by its shoots, which are fur- 

 nished with leaves in tufts or bundles, that generally run 

 along on the surface of the rest of the herbage, and is occa- 

 sioned, apparently, by the cattle, which eat the other her- 

 bage, and leave the scattered shoots of the tufted-leaved 

 bent untouched. It is a very common grass on poor, light, 

 but moist soils, incumbent on clay, that have long been 

 under pasture. This and the woolly soft-grass, in some 

 parts of the country, are termed winter-Jog. 



From the above details it will appear to be the least va- 

 luable of the bent-grasses that have been mentioned. 



Flowers in the first and second weeks of August, and 

 ripens the seed in the end of the same month. 



AlRAJlexuosa. Zig-zag Hair-grass, Wavy Mountain Hair- 

 orass.
