200 HOUTUS GRAMINEUS WO B URNEN S 1 S. 



plant at this period or shortly after ; for when the seed is 

 ripe, the straws contain but a small proportion of nutritive 

 matter ; and the seed itself contains little more than the 

 plants afforded at the time of flowering, the difference 

 being as 7 to 5 : which seems to prove that the culms and 

 leaves, a little after the time of flowering, contain nearly all 

 the nutritive matter which passes into, or constitutes the 

 substance of the seed. 



It flowers in the third week of June, and the seed is ripe 

 about the end of July. 



AGROSTIS canina capillaris. Fine-panicled Brown Bent. 



Variety with a hair-like panicle, spreading, flexuose, ca- 

 lyces subulate, equal, smooth, coloured. This variety 

 is nearly akin to the agrostis canina Jascicularis ; it 

 grows pretty common in some parts of Woburn Park, 

 where the soil is siliceous. 



Native of Britain. Root perennial. 



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

 a sandy loam is 4,764 lbs. per acre. 



The above details afford no proofs of the value of this for 

 agricultural purposes. It is found in a wild state, on heaths 

 chiefly. I never observed that even hares cropped its herb- 

 age. Its manner of growth is similar to that of the agrostis 

 Jascicularis, only that the leaves are not produced in bundles 

 or tufts, which is so distinguishing a feature of that grass. 

 It is seldom combined with any other species of grass, but 

 grows in detached patches on moors and heaths. 



It flowers about the beginning of August, and the seed is 

 ripe about the end of that month. 



ALOPECURUS geniculatus bulbosus. Bulbous -rooted 

 knee-jointed Foxtail-grass. 



Qf)s. — Root of this variety bulbous ; awns longer than the 

 blossom; sheaths wider than the thickness of the straw; 

 anthers purple, and changing to a brown-yellow. 



Native of Britain. Perennial.
