This grass sends forth flower straws during the 

 whole season; the latter-math contains nearly an equal 

 number with the flowering crop. It is subject to the 

 rust, but the disease does not make its appearance till 

 after the period of flowering; it affects the whole plant, 

 and at the time the seed is ripe the leaves and straws 

 are withered and dry. This accounts for the superior 

 value of the latter-math over the seed crop, and points 

 out the propriety of taking the crop when the grass is 

 in flower.
