The proportional value which the crops, at the 

 time the seed is ripe, bear to that at the time of flower- 

 ing, is as 4 to 9.

This species is annual, and no valuable proper- 

 ties have as yet been discovered in the seed. It is 

 only noticed on account of its being frequently found 

 in poor grass lands, and sometimes in meadows. It 

 appears from the above particulars to possess nutritive 

 powers equal to some of the best perennial kinds, if 

 taken when in flower; but if left till the seed be ripe 

 (which, from its early growth, is frequently the case), 

 the crop is comparatively of no value, the leaves and 

 straws being then completely dry.
