Flore de France, par M. Grenier et M. Godron. Vol. I. Pcirt L 

 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 Ranunculacece, includes thirty Natural 

 Orders, concluding with Coriaricd. The language is French ; the 

 plan similar to that of Koch's * Synopsis Florae Germanicse ' 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 

 England to Wisconsin and south to Ohio and Pennsylvania inclusive, 

 arranged according to the Natural System. By A. Gray, M.D. 

 Boston, 1848. r2mo. 710 pages. 



Dr. A. Gray has here supplied botanists with a very valuable con- 

 densed account of the plants of the northern part of the United 

 States. It includes the flowering plants and ferns by Dr. Gray him- 

 self, and the mosses and liverworts from the pen of Mr. W. S. Sul- 

 livant. Mr. John Carey has elaborated the genera Sali^\ Populus 

 and Carex. 



The plan of the book is similar to Koch's * Synopsis Florae Ger- 

 manicse,' 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 woik ; the name of 

 its author is a sufliclent guarantee of that being the case. It is just 

 what was wanted by the European botanist, since, in conjunction with
