On liying grasses. Common. [Low. & Mid. Carolina,] 



The grass affected with this carious parasite mimics the reed mace {Typha) 

 in its appearance. It surrounds the stalks to an extent varying from half an 

 in. to 2 in., is white in its earliest state, but in a few days acquires the 

 orange-yellow colour of maturity.— /oA/i5^i^J. J5er. (-f'lj. 370.)
