426 HARPER: VEGELATION OF THE COASTAL PLAIN 
tioned in such a rudimentary description as this, but interested 
readers can easily find them.* 
The plants which I was able to recognize more than once in 
this region are as follows. 
TREES 
34 Pinus rigid 3 Quercus marylandica 
8 Chamaespari thyoides 3 Quercus Prinus 
7 Pinus ech 2 Nyssa sylvatica ? 
4 Betula Seti. 2 Quercus alba 
3 Acer rubrum 
SHRUBS 
16 Quercus tlicifolia 2 (Sassafras variifolium) 
2 Comptonia peregrina 
HERBS 
19 Pteris aquilina 3 Osmunda cinnamomea 
4 Anchistea virginica 2 Habenaria en 
4 Lilium superbum Lophiola a 
The species appearing for the first time in this list are Pinus 
rigida, Quercus Prinus, Q. ilicifolia, Comptonia, Lilium superbum, 
and Lophiola. 
In botanical manuals one frequently sees the ranges of certain 
plants given as “Pine-barrens, New Jersey to Florida,” etc., just 
as if the same kind of country extended all the way. But on this 
trip it was strongly impressed on me that the New Jersey pine- 
barrens are quite different from the southern ones. The two 
kinds do not even intergrade, for one can travel the whole length 
of the Delaware peninsula, from the fall-line to the coast, without 
seeing any pine-barrens of either kind. + 
The differences between northern and southern pine-barrens 
seem to be more numerous than the similarities. Consider- 
ing only characters observable from a train, the similarities 
are about as follows. Both are in the coastal plain and have 
sandy soil, with pioneer vegetation subject to frequent fires. Pines 
are the dominant trees, and oaks usually form a sort of lower story. 
Sour bogs and swamps are frequent. Both regions are compara- 
tively thinly settled, and still have more forests than fields. 
*There is however one work that deserves special mention, namely, the report 
on forests that accompanied the annual report of the state geologist of New Jersey 
for 1899. This i volume of 327 pages, containing important contributions by 
Vermeule, Pinchot, Hollick, Gifford, and others, together with numerous maps and 
illustrations.
