Apparently annual. Stem slender, about 2 feet high, slightly angled, 

 glabrous- Leaves oj)posile, about an hich long^ with the margms a little 

 rough. Peduncles opposite and ahernate, and as they frequently bear 

 leaves and brauches,they may all bo considered as real branches bearing ter- 

 mnial flowers, but to the eye the upper ones resemble simple peduncles 

 about 2 inches long. Calt/x tnmcate, teeth subulate, small, acute, Co- 

 rolla rather small, purple, white in the tube, with 2 yellow streaks, hairy, 

 the border equally 5-cleft, segments rounded, fringed. Filaments shorter 

 than the corolla, the longer pair villous. AntJiers sagittate, very villous 

 and as in all of this genus 2 cleft and mucronate at base, Sfyle about as 

 Jong as tlie stamens. Stigma thick, extending along the side of the style. 

 Capsuirs ovate. 



Grows in damp lands along the margins of swamps and dry galls.
