cent, particularly along the margins. Florets of the ray about twelve, ob- 

 long, narrow, white. Seeds pubescent along the angles. Papims double. 



If this plant should be made the type of a new genus, the species will pro- 

 bably muhiply. I have by me varieties, with the leaves simply acute, not 

 acuminate, the lowest rather obtuse, the corymbs small; and with leaves 

 acuminatej with leaves green on both sides and slightly glaucous underneath. 



Glows on the edges of swamps, in the middle and upper districts of Ca- 

 rolina.
