Flore de France, par M. Grenier et M. Godron. VoI. I. Part 1. 
Paris, 1848. 8vo. 
We have much pleasure in recommending to the notice of our bo- 
tanical readers this first portion of what promises to be a most valu- 
able work. Now for the first time there is a probability of our pos- 
sessing a general French flora of a truly scientific and comprehensive 
kind. All the former attempts at such a work have been deficient 
in one or other of those respects : — the best of them, although high 
in scientific character, is very incomplete in other points. Many 
large districts of France seem long to have suffered an almost total 
neglect from botanists, and it is only of late that the publication of 
good local floras, and the more general distribution through France 
of that botanical knowledge which was so long confined, in a great 
degree, to Paris, has provided the requisite materials for a complete 
flora. 
The work before us is arranged very nearly in accordance with the 
system of DeCandolle as developed in his ‘ Prodromus and this 
first part, commencing with Ranunculaceae , includes thirty Natural 
Orders, concluding with Coriarire. The language is French ; the 
plan similar to that of Koch’s ‘ Synopsis Florae Germanicae ’ and 
Babington’s ‘ Manual of British Botany.’ 
Were we to attempt a detailed examination of the contents of this 
work, we should extend far beyond our limits ; we therefore merely 
remark, that the apparent tendency of the authors is to divide species 
rather more than seems desirable to us. 
This work is as necessary to the student of British botany as 
Koch’s ‘ Synopsis.’ Both of them ought to be in the hands of all 
who aspire to a higher rank than mere collectors. We look anxiously 
for the continuation of this flora. 
A Manual of the Botany of the Northern United States, from New 
Engla7id to Wisconsin and south to Ohio and Pefinsylvania inclusive, 
arranged according to the Natural System. By A. Gray, M.D. 
Boston, 1848. 12rno. 710 pages. 
Dr. A. Gray has here supplied botanists with a very valuable con- 
densed account of the plants of the northern ])art of the United 
States. It includes the flowering plants and ferns by Dr. (^ray him- 
self, and the mosses and liverworts from the pen of Mr. W. S. Sul- 
livant. Mr. John Carey has elaborated the genera Salix, Populus 
and Carex. 
The plan of the book is similar to Koch’s ‘ Synopsis Florae Ger- 
manicae,’ and must prove as useful to the student of the plants of its 
province, as that work has been found to be by the botanists of 
Central Europe. 
We need scarcely add that it is an excellent work ; the name of 
its author is a suflicient guarantee of that being the case. It is just 
what was wanted by the European botanist, since, in conjunction with
