Not above a span high; flowers pale blue or white- Pursh. 



I have not been able to refer to the figure of Lara, (illust. t. 681. f. 4 ) 

 for this plant, but it appears to me probable that it is only the preced- 

 ine species which he has described under this name, perceiving that It did 

 not correspond with the original description of the £. Philadelphicum. 



Grows in Carolina. 



Flowers July and August. Pursh.
