Hab. On Eding's Island, near Charleston, South Caro- 
lina, Elliott ; and near St. Mary's, Georgia, Dr. Baldwin. 
"A rare plant in South Carolina and Georgia, but becomes 
predominant in the live-oak forests south of St. John's river, 
in Florida." Baldw. MS. 
Obs. This plant has not fallen under my notice. It does 
not exist in that portion of Dr. Baldwin's herbarium which 
has come into my possession. Mr. Elliott's description is 
brief and incomplete, but sufficient to show that the plant is a 
very distinct species.
