HARPER: DISTRIBUTION OF PLANTS OF THE COASTAL PLAIN 597 
EUPHORBIA ERIOGONOIDES Small. 
In 1906 I found this in sand along a railroad near Florence, 
South Carolina,* and three years later, almost to the hour, I 
found it in similar situations about 50 miles due north, near 
Hamlet, North Carolina, which is another state for it. 
STILLINGIA AQUATICA Chapm. 
In a pine-barren pond just north of Luray, Hampton County, 
South Carolina. Although this was credited to South Carolina 
(exact locality not specified) by its author, I have never seen it 
mentioned in local floras of that state (there have been very few 
published, though, since this species was described, half a century 
ago), or even seen a specimen from there. This is therefore prob- 
ably the first definite record for it in South Carolina, as well as its 
northernmost known station. As in the case of Pluchea imbricata 
and Sabbatia decandra, I had not previously seen it northeast of 
Tattnall County, Georgia. 
POLYGALA CyMosA Walt. 
Common in ponds in Hampton County, South Carolina, and 
seen twice in Bladen County, North Carolina, somewhat like 
Oxypolis filiformis (see above). I did not see it north of Wilming- 
ton in previous years, and Kearney did not find it in the Dismal 
Swamp region. There must be a considerable gap in its range 
between North Carolina and Delaware, somewhat like that be- 
tween the Oxypolis fliformis and its variety Canby. 
POLYGALA LUTEA L. 
As in 1906, I found no trace of this in South Carolina. 1 
noticed it first near Hamlet, and commonest between Wilmington 
and Verona, and New Bern and Mackey’s Ferry. 
AMORPHA HERBACEA Walt. 
Both in 1906 and 1909 I saw this only in dry pine-barrens in 
the Cape Fear region. It grows in Georgia, but is probably rare 
in South Carolina. 
Cytisus scopartius (L.) Link. 
I saw this several times on the railroad right-of-way on the 
Yorktown peninsula of Virginia, but as I did not then realize 
what it was (never having seen it before), I could not very well
