In wet gravelly woods in Illinois and Virginia. 1/ . July. 

 V. V. This singular and elegant grass I found on the 

 islands of Roanoak river in North Carolina, and ob- 

 served it catching flies in the same manner as Dioncca 

 muscipula : the valves of the corolla are nearly of the 

 same structure as the leaves of that plant. I commu- 

 nicated specimens with this particular circumstance to 

 Dr. B. S. Barton of Philadelphia, who has made men- 

 tion of it in a paper on the irritability of plants.
