approbation. It is to be hoped that their venture (for it is a venture 
to place upon the market such an expensive book as this must have 
been at such a low price) will prove no less profitable financially than 
it has proved excellent from a scientific and bibliographic point of view. 
We expect an immediate adoption of the book by all the leading 
colleges in the country, not only because of the importance of the 
subject of which it treats, but also because of its excellent qualities as 
a treatise.—W. S. B. 
Britton’s Catalogue of New Jersey Plants.!—This thick 
volume of 642 octavo pages is one of which the botanists of the coun-

attempted in the United States. From the table in the end of the 
volume we learn that there are : 
Anhopnyle.. 0, ;, 1,919 species and varieties.

The preface states that “the present work is based, so far as the 
flowering plants, ferns, and fern allies are concerned, on specimens 
actually seen and examined by myself, and contained in the State 
Herbarium above alluded to, or in other collections of repute. The 
lists of lower plants have been supplied by specialists of high reputation 
and authority.” Itisthus an authoritative catalogue, which is suscep- 
tible of correction, if need be, at any time in the future. 
In discussing the distribution of the plants of the State the author 
refers to the rocky and mountainous areas of the northeastern portion, 
the glacial drift of the same region, the lower level of the southern 
part, and the much greater sandiness of its soil. ** Our flora may thus 
be divided with considerable accuracy into a northern and a southern, 
whose present distribution has been determined by differences of soil 
and climate.” ese are separated by the glacial terminal moraine. 
“ Besides these two main divisions of our flora, there is another, which 
may be termed the marine and coast group of plants,—species and var- 
ieties especially characteristic of the sea-beaches and salt and brackish
