range its favorite habitat seems to be stagnant or gently flowing 
non-calcareous water whose level does not vary more than a foot 
or so during the year. 
SERENOA SERRULATA (Michx.) B. & H. First seen in Chatham 
County, Georgia, about six miles beyond where the Savannah 
River was crossed. It is reported from South Carolina, but in 
that state is perhaps confined to the southernmost county, Beau- 
fort, in which I have. never been. 
SaBAL PALMETTO (Walt.) R. & S. Seen only in the marshes 
of the Little Ogeechee River, Chatham County, Georgia. The 
rest of the way I was evidently too far inland for it. 
SABAL GLABRA (Mill.) Sarg. First noticed in the Savannah 
River bottoms near Hardeeville, S. C. 
CLADIUM EFFUSUM (Sw.) Torr. Seen only between Callahan 
and Jacksonville, Florida, in a few shallow swamps where lime- 
stone is assumed to be near the surface. In other states it seems 
to be almost confined to estuarine marshes near the coast, but in 
Florida it grows in nearly every county. 
Taxopium. Both species were first encountered this time in 
Barnwell County, South Carolina, T. imbricarium in the northern 
edge of the county, and T. distichum just south of the county 
seat. Both extend far down into Florida.* 
CHAMAECYPARIS THYOIDES (L.) B.S.P. Noticed twice along 
creeks in the sandhills of Lexington County, South Carolina, about 
ten miles southwest of Columbia. 
Juniperus. Whether the Juniperus which is indigenous 
near the southern coast is J. virginiana or J. barbadensis, or 
both, I have never been able to determine. Trees of this genus 
were seen in the Little Ogeechee marshes, Chatham County, 
Georgia, and in two supposedly calcareous swamps between 
Callahan and Jacksonville, Florida. (I afterwards collected 
specimens at the locality nearest Jacksonville.) It is decidedly 
rare in eastern Florida. 
PINUS GLABRA Walt. Seen first in the upper edge of Hampton 
County, South Carolina, and last just north of the Ogeechee 
River in Georgia. Farther south the boundary of its range 
seems to diverge considerably from the coast.
