The frequency of Pinus palustris has of course been diminished 
by the same causes previously mentioned. About ten years ago, 
when that part of the Seaboard Air Line between Columbia and 
Hamlet had just been completed, this pine should have been seen 
nearly every mile, or about 100 times. Of the other plants associ- 
ated with it here, Polycodium, Eriogonum, Baptisia, and Nolina 
were seen only in South Carolina on this trip, and they probably 
do not extend any farther north; while Dasystoma pectinata, 
Carduus repandus, and a few species seen less than three times 
were noticed a few miles over the state line in North Carolina, 
but no farther. 
From about Laurel Hill to Rosindale, N. C., a distance of 63 
miles, the country is mostly rather level, damp and sandy, with 
no ponds, but many shallow bogs and non-alluvial swamps, and 
a few pocosins toward the southeast. (The first few miles, and 
indeed most of Scotland County, is more hilly than the rest, and 
should perhaps be correlated with the parts of Orangeburg County, 
5. C., passed through the day before, but the hilly part is so limited 
that it will not introduce any serious error to include it with the 
rest.) This kind of country, with slight modifications, seems to 
extend southeastward most of the way across South Carolina,
