Low prairies, not common. The plant is usually dioecious 

 with us, the fertile and sterile plants growing in separate 

 patches. It seems to be very tenacious of life, several patches 

 in the author's door-yard flowering and perfecting fruit every 

 year in the hard packed soil along with knot weed {Polygo- 

 num aziculare L.). The plant varies from 6 to 10 inches in 

 height on higher ground, to 2 feet high in moister situations.

Very common throughout in woods, and occasionally on 

 low prairies. In the latter situation the plants grow in larger 

 stools, are more slender and lighter colored, the spikes 

 smaller. In deep, rich woods the plants are a darker green 

 throughout.
