Rhexia Alifanus, Polygala ramosa, Campulosus aromaticus, and 
Lilium Catesbaei were seen oftener along my 1906 route through 
this region than on that of 1909, and Gordonia, Nyssa biflora, 
Quercus Catesbaei, Cornus florida, Taxodium imbricarium, Acer 
rubrum, Quercus falcata, Smilax laurifolia, Myrica pumila, Ilex 
glabra, Phoradendron, Trilisa, Oxypolis, and Osmunda cinnamomea 
at least four times as often on the second trip as on the first, which 
seems rather singular. Some of these cases may be due simply 
to my own carelessness, but others probably indicate local irreg- 
ularities of distribution. Other evidence of such irregularities is 
found in the fact that in each year I noted several fairly abundant 
species in this region either on one side or the other of Wilmington 
and not on both. It would be very interesting if some other 
botanist would go through the same region at the same season, 
either by one of the same routes or by a different combination of 
routes (Wilmington has five lines of railroad radiating from it, 
all passing through the pine-barrens for approximately the same 
distance), and take notes in the same way and compare his results 
with the above. 
It happens that all the species here recorded from the Cape 
Fear pine-barrens occur also in Georgia} (and with approximately 
the same relative frequency), while several of them, such as Gor- 
donia, Persea, Cyrilla, Myrica pumila, Amorpha, Aristida stricta, 
*Probably X. flexuosa (X. torta of many authors) and one or two o 
tFrom which it follows that the local species peculiar to this region are either 
rare, or inconspicuous in midsummer (or both), or else that I do not know them well 
enough to recognize them from a moving train.
