DurRING THE SUMMER OF IQOI 291 
Virginicum, Ludwigia sphaerocarpa, Ludwigiantha arcuata, Ceph- 
alanthus occidentalis, and a small species of Eleocharis. The 
Cephalanthus is probably attached to the bottom, but the other 
species have no direct connection with the soil. 
Around both Cane Water and Open Ponds, and all the way 
between them, the soil is of the Columbia sands, loose and dry, 
giving rise to a flora not unlike that of the sand-hills of southeast 
Georgia. In such situations numbers 1214 and 1215 were col- 
lected. ; 
From Cane Water Pond we retraced our steps to Open Pond, 
followed the road from there toward Bainbridge about two miles, 
and then went back to Whigham by a. different road. Soon after 
turning back toward Whigham we passed a limited area of very 
dry white sand, similar to that of the rosemary sand-hills of Eman- 
uel County and containing a few of their characteristic species, 
which were not seen elsewhere in southwest Georgia (nos. 1216, 
1217). 
From Whigham I went alone on August 14 to Saffold, in the 
southwestern corner of Early County, on the Chattahoochee River, 
and collected along and near the river that afternoon and the next 
morning (nos. 1218-1232). The banks of the Chattahoochee at 
this point, about thirty miles from its confluence with the Flint 
and a hundred feet above sea level, are only about half as high as 
they are near Omaha, but still quite steep. As they are here sub- 
ject to occasional overflow the flora is rather different from that 
farther up. Rhus copallina, Aralia spinosa and Bumelia lyctioides, 
species which elsewhere are usually shrubs, here become truly 
arborescent. Specimens of Ava/za with trunks six inches in diam- 
eter and twenty-five feet tall and of Bumelia eight inches thick and 
about fifty feet tall were observed. 
There are several small lime-sinks between the station and the 
river, though this -is very near the inland edge of the lime-sink 
region. A short distance north of the station is a rather remark- 
able feature for this part of the state, a steep rocky wooded hillside, 
sloping toward the river, with of course a rather peculiar flora. 
The outcropping rocks, which are very hard and siliceous, are 
clothed with mosses and lichens, and Asplenium platyneuron grows 
in their crevices, just as it does in the mountainous parts of the
