290 Harper: BOoTANICAL EXPLORATIONS IN GEORGIA 
of the most beautiful natural features in South Georgia. I know 
of no other such waterfall in the entire coastal plain of the eastern 
United States. The side of the sink opposite the falls is not too 
steep to allow of an easy descent to the bottom, and we spent a 
couple of hours at this interesting spot on the morning of August 
12 (nos. I190-1194). 
On leaving Forest Falls we walked southwestward toward 
Bainbridge about nine miles (nos. 1195-1201), to visit a pond 
which is also illustrated in the bulletin just mentioned. There it 
is called Fairview Lake, but we found “ Open Pond” to be the 
name in current use in the vicinity. This pond is about half a 
mile in diameter, and takes its name from the fact that, unlike 
most of the ponds of the coastal plain, there is no vegetation show- 
ing above its surface except a few bushes near the shore. The 
water is unusually clear, and the shore is sandy, affording a habi- 
tat for several very interesting plants (nos. 1202-1206). In all 
these respects it resembles very much some of the ponds of New 
England. 
Early the next morning we explored another pond about the 
size of Open Pond and two miles north of it, of which we had been 
told on the previous day. This latter is known as ‘‘ Cane Water 
Pond,” and is said to derive its name from the abundance in it of 
maiden-cane (Panicum digitarioides). It is very different from Open 
Pond, being surrounded by cypress (Zaxodium imbricarium) 
swamps and filled with a luxuriant aquatic vegetation. Here we 
had the use of a boat, so were able to explore the pond somewhat 
thoroughly (nos. 1208-1213). Cane Water Pond is remarkable 
for containing a representative of each of our five North Ameri- 
can genera of Nymphaeaceae, viz., Cabomba, Brasenia, Nelumbo, 
Nymphaea and Castalia. The Brasenia and Nelumbo are of 
course the same species as found in the northern states, but the 
other three genera are represented by different forms which will 
be mentioned later. The Mel/uméo is quite rare, but the other four 
are abundant and their floating leaves together with those of Lzm- 
nanthemum aquaticum serve to cover the surface of the pond very 
_ densely, leaving only two or three open spaces a few yards across. 
Another interesting feature of Cane Water Pond is the presence in 
_ it of several floating islands, composed principally of Triadenum
