HARPER: DISTRIBUTION OF PLANTS OF THE COASTAL PLAIN 595 
Croom in his flora of New Bern and vicinity, published in 1837, 
stated distinctly that he had not seen it farther north than the 
counties of Carteret and Onslow. (It was in Onslow County that 
I last saw it.) And Kearney places its northern limit still farther 
south. 
SABBATIA DECANDRA (Walt.) Harper. 
In pine-barren ponds between Garnett and Scotia, Luray and 
Gifford, in Hampton County, South Carolina. Walter's original 
specimens presumably came from South Carolina, but no 19th 
century botanist seems to have seen it northeast of the Canoochee 
River.* Nearly all the existing herbarium specimens are from 
Florida. 
PoOLYCODIUM CAESIUM Greene, Pittonia 3: 325. 1898. 
On the fall-line sand-hills of Orangeburg, Lexington, and Rich- 
land counties, South Carolina. 
OXYDENDRON ARBOREUM (L.) DC. 
On this trip seen first near Verona, North Carolina (very 
common between there and New Bern), and last about three miles 
east of Williamsburg, Virginia. Three years before, I saw it only 
between Tarboro, N. C., and Windsor, Va., a still smaller range. 
Daucus Carora L. 
Noticed first at Elizabeth City, North Cas and then 
nearly everywhere north of there. The ‘‘carrot weed” reported 
from Wayne, Greene, Craven, Martin,and Chowan counties in 
Kerr’s report on the cotton production of North Carolina (Tenth 
Census, vol. 6, 1884) may be the same thing. In Georgia it is 
common enough in some parts of the Piedmont region, but I do 
not remember seeing it in the coastal plain. Some interesting 
notes on the distribution of this European weed in the eastern 
United States were published several years ago by L. H. Dewey.t 
OXYPOLIS FILIFORMIs (Walt.) Britton. 
Common in shallow ponds in Hampton County, South Caro- 
lina, and in moist pine-barrens in the eastern part of Bladen 
County, North Carolina.. This species has long been credited to 
Virginia, apparently on no other evidence than a very poor speci-
