572 MONOECIA TRIANDRIA. 



flowers dioecious; Spikes 

 branching, clustered, by 



ribus dioicis; spicis sub- 

 ramosis, glomeratis, 



geminatis^ petiolo Ion- 1 pairs, longer than the 

 gioribus. E. I petioles.

s 



Stem tliree to four feet high, obtusely four-angled, pubescent. Leaves op- 

 posite, ovate lanceolate, sonietinaes obtuse, soinetimes slightly acuminate, 

 acutely serrate, strongly nerved and veined, sprinkled with hairs on the upper 

 surface, very pubescent underneath along the veins. Petioles one to two 

 inches long, pubescent and ciliate. Flotaers in compact approximate clus- 

 ters, on branching spikes. Spikes two from each axil, in all of my speci- 

 mens longer than the petioles, sometimes nearly as long as the leaf. Cal^x 

 somewhat hairy. ' 



In specimens of this plant which I received from Dr. Muhlenberg him- 

 self, and in others sent me from our upper country, the leaves are never cor- 

 date, and the spikes uniformly longer than the petiole. 



Grows in wet soils in the upper districts of Carolina and Georgia. 



Flowers July — August.
