The pine barren region of New Jersey may be divided into two portions, 
one comprising the coniferous area and the other a portion of the tran- 
sition area, where the conifers encroach on the deciduous vegetation. The 
coniferous, or pine-barren belt is a strip of land sixty miles long by from 
eight to twenty miles wide. Its soil varies from a light sandy loam to clean 
beach sand. Its streams rarely overflow their banks, there are peat bogs, 
barren plains marl beds, hardwood swamps and cedar swamps which diversify 
the monotonous landscape. Little diversity in either geology or topography is 
presented in this territory. The soil has an almost uniform character through- 
out and the surface irregularities are relatively small. The coniferous vegetation 
is conterminous with the northern border of the Tertiary gravels, sands and 
sandy clays, and it is limited on its southern and eastern borders by a fringe 
of modern sand beaches and salt marshes, while southwestward, it extends 
beyond the limits of the state, while the tension zone includes practically the 
whole of the Cretaceous plastic clays and the Cretaceous and Tertiary clay- 
marls and marls. 
The following list according to Witmer Stone (Proceedings Academy Natural Sciences = 
Philadelphia 1907: 452—459) includes the peculiar pine-barren species and those which oc
