writing, 
With regard to this plant Mr. Harper writes as follows: 
“Nymphaea fluviatilis seems to be quite common in creeks, 
small rivers, and the swamps of large rivers, but apparently 
never in ponds, in the coastal plain. I have seen it in the 
Savannah River swamp in the southeastern corner of Effingham 
County, in Rocky Comfort Creek near Louisville, in Buckhead 
Creek near Millen, in the Ogeechee River near Chal ker, Millen, 
Rocky Ford, Dover, and Meldrim, in the Canoochee at the type locality, in the 
Ohoopcee near Ohoopee and Reidsville, in the swamps of the Altamaha near Doctor- 
town and Barrington, in the Oconee swamps near Mount Vernon, in the little Oemul- 
gee near Lumber City, in Echeconnee Creek near its mouth (on the line between Bibb 
and Houston Counties), in the Ocmulgee River swamps near Abbeville, in the With- 
lacoochee near Nashville, and in the Flint River swamps in Crawford County near 
Everett.”’
