SYNGENESIA SUPERFLUA, 
cent, particularly along the margins. Florets of the ray about twelve, ob- 
long, narrow, white. Seeds pubescent along the angles. Pappus double. 
If this plant should be made the type of a new genus, the species will pro- 
bably multiply. I have by me varieties, with the leaves simply acute, not 
acuminate, the lowest rather obtuse, the corymbs small; and with leaves 
acuminate; with leaves green on both sides and slightly glaucous underneath. 
Grows on the edges of swamps, in the middle and upper districts of Ca- 
rolina. 
Flowers August — September.
