376 Harper: COASTAL PLAIN OF THE CAROLINAS 
in abundance, being apparently most abundant where P. padustris 
is least so (in Virginia and the upper third and lower tenth of the 
coastal plain of South Carolina, for instance), and vice versa. 
PINUS SEROTINA Michx. 
In the Carolina coastal plain this tree is almost as frequent as 
P. Taeda, though generally much less abundant. In a few places, 
however, particularly around Ashton, in Pender County, N. C., 
it is almost the only pine in sight over a considerable area. It is 
much more particular as to habitat than P. Zaeda, being chiefly 
confined to pocosins and other sandy bogs, and avoiding the least 
trace of alluvium. 
On this trip I saw a good deal of it in Nansemond County, 
Virginia, as in 1903,* and a little in Sussex County and perhaps 
a specimen or two in Chesterfield. In the northern edge of Dis- 
mal Swamp, along the N. & W. Ry., a few miles east of Suffolk, 
are many individuals at least a foot in diameter and forty feet tall. 
I did not notice until very recently that Mr. Ashe + mentioned 
the occurrence of this species in Virginia long before I did, but in 
such an inconspicuous way that it has been overlooked by nearly 
every subsequent writer. An interesting problem which still 
awaits solution is to determine how far north P. serotina really 
extends, and whether it overlaps or intergrades with its nearest 
relative P. rigida. 
TaxopIuM IMBRICARIUM (Nutt.) Harper 
Noted in six counties in South Carolina (especially in Barn- 
well, Hampton and Williamsburg), but in only two in North 
Carolina (Columbus and New Hanover). It is common in places 
along the car line between Wilmington and the beach, where some 
specimens fully a foot in diameter and forty or fifty feet tall were 
observed ; so it seems strange that Wood & McCarthy knew it 
from only one spot in that county. After leaving Wilmington I 
did not see any more of this tree, strange to say, unless a few 
specimens in the northern edge of Dismal Swamp, which I did
