A FLORA OF THE NEW JERSEY PINE BARRENS.— Mr. Witmer Stone's! 
flora of southern New Jersey is one of the notable local floras of 
recent years. In the author’s own words, “it places on record the 
present condition and history of one of the most interesting botanical 
areas in the United States,— the Pine Barrens of New Jersey." The 
introductory chapter is a detailed statistical study of the entire 
indigenous flora of southern New Jersey. It presents a division of 
the species into four groups; (1) the species of wide range north and 
south of New Jersey, (2) northern species which reach their southern 
limit in or near southern New Jersey, (3) coastal plain species which 
reach their northern limits between southern New Jersey and the 
northeastern extension of the coastal plain in Massachusetts, and 
(4) species of local distribution in or near southern New Jersey. A 
further analysis shows the composition of the flora of each of the five 
distinct floral districts; (1) The West Jersey, or middle district 
(covering the Delaware Valley region south of Trenton, and also the 
country below the fall line and north of the Pine Barrens), (2) the 
Pine Barrens, (3) the coastal strip, (4) the Cape May district, and 
(5) the maritime district. The floral analysis is similar to that in 
Prof. Fernald’s recent discussion of the origin of the Newfoundland 
flora (v. RuoponA XIII, p. 135 et seq. 1911) and is likewise 
accompanied by maps illustrating the several types of distribution. 
The author concludes that in the New Jersey Pine Barrens we have 
some of the sand and bog elements of a formerly wide-spread austral 
flora which has been largely “superseded” over most of the coastal 
plain by more “advanced” elements of similar origin. Mr. Stone 
weakens his own conclusion by classing many plants with floras to which 
they certainly do not belong. "Thus, the typical pine-barren Schizaea 
pusilla and Corema Conradii are considered by Mr. Stone as boreal 
species which have been driven south, whereas there seems to be no 
escape from Fernald’s conclusion that they are of austral origin. In 
listing the southern elements in the pine barren flora, Mr. Stone fails 
to distinguish between species which in the south are coastal only
