in the keys, for purposes of identification. This way of treating 
them corresponds with current ornithological usage, and is a 
decided improvement on the practice of most botanists. Since 
the author has gone ahead of his botanical predecessors to the 
extent of excluding species known to have been introduced from 
foreign countries, one can hardly criticize him for not going a 
step farther and excluding species which are commonly supposed 
—though sometimes on insufficient grounds—to be native in other 
parts of the northeastern United States, when there is no good 
evidence of their indigeneity in southern New Jersey. (Several 
examples are mentioned on page 100, and numerous others in 
the catalogue.*) He does indeed state in many such cases that 
the species in question can hardly be native in the pine-barrens, 
and implies that they might be equally foreign to the other parts 
of his territory. 
The author's ornithological training is revealed in his methods 
of citation. Wherever a species has been transferred from one 
genus to another the author of the new binomial is ignored, a 
practice more justifiable under the “Rochester” rules of two 
decades ago, which gave absolute priority to specific and varietal 
names, than under the rules of botanical nomenclature now in 
vogue, which allow some classes of exceptions. Like most zo- 
ologists and some botanists, he decapitalizes all specific names, 
regardless of origin, and uses Roman numerals for volume num- 
bers. (In citing periodicals in footnotes the year is often sub- 
stituted for the volume number, as was the custom for a number 
of years with the proceedings of the institution of which he is 
curator.) Each species listed is accompanied by a citation of 
its original description and type-locality (these data not merely 
copied from another book, but verified from the originals in 
nearly every case; see p. 34), and references to the pages of a 
few previous floras of the same region where it is mentioned. If 
it has been listed under different names in any of these other 
works those names are also given. Every accepted species is 
also given an English name (a fictitious one if no bona-fide one 
is known), in which particular the author is again following 
ornithological usage.
