 smaller flowers, and perfectly inodorous. — Black Lake, near Macon. 



A beautiful plant, distinguished by the delicious odor of its large white flowers. The 

 genus is more properly the indigenous production of the East Indies — several species 

 growing there, and but one on the continent, of North America. The plant has been 

 Bometimes employed in medicine, but we believe has pretty much passed from use.
