Native of Georgia, in marshes on the banks of the river 
Ogeechee. A’mmi costatum, Ell. sketch. 1. p. 350. Said to 
be nearly allied to the species, but differs according to Elliot, in 
the plant being of taller stature, 4-5 feet high, not 1 or 2 feet 
high, as in the species, and in the time of flowering, which is in 
autumn, and not in the spring, and in the leaves of the involucel 
being equal in length to the umbellules.
