198 Bibliography. 



with a complete index to that invaluable work, down to the first part of 

 the 7th volume. We may here state, that the 8th volume of De Can- 

 dolle's Prodromus was probably published at Paris in December last, 

 and will doubtless reach us in season for a notice in the ensuing num- 

 ber of this Journal. A. Gr. 



7. Ledeiour^s Flora Rossica. — The first part of this work, published 

 in 1841, was announced in a former number of the Journal, (Vol. xliii, 

 p. 188.) The second, published in 1842, comprises the natural orders 

 from Violacecn to Geraniacea, following the series of De Candolle's 

 Prodromus. Much the largest family of this portion is the Caryophyl- 

 lacece, especially the Alsinece, which are here elaborated by their assid- 

 uous monogi-apher, Dr. Fenzl, of Vienna, in such a manner as satisfac- 

 torily to clear up the doubts and obscurities that rested on many of our 

 northern species. We hope soon to be able to announce the publica- 

 tion of Dr. Fenzl's complete revision of this family. The third part of 

 the Flora Rossica, which completes the first volume, (of 786 pages,) 

 was published in 1843, and has just reached us. It continues the series 

 from Balsaminece. to the end of Leguminosce ; the latter being, of course, 

 much the largest order of the Exogense Polypetalse. The Russians are 

 actively engaged in exploring their remote Asiatic provinces, but their 

 American possessions do not appear to have been visited of late years 

 by any botanist. Consequently, this work has thus far thrown very little 

 additional light upon that portion of the flora of our own continent.

8. A Manual of British Botany, containing the Flowering plants and 

 Ferns, arranged according to natural orders ; by Charles C. Babing- 

 ton, M. A., F. L. S., etc. London, Van Voorst, 1843. pp. 400, 

 12mo. — This new compendium of British plants is formed on the model 

 of Koch's excellent Synopsis Flora Germanicce, (which we are glad to 

 learn is now passing to a second edition.) The author has been highly 

 praised for his knowledge and acumen, even by those who are far from 

 agreeing with him in many of his conclusions respecting the validity of 

 particular species. Mr. Babington found it necessary to make a careful 

 comparison of the British with the continental flora ; " for it appeared 

 that in very many cases the nomenclature employed in England was 

 different from that used in other countries, that often plants considered 

 as varieties here, were held to be distinct species abroad, that several of 

 our species were looked upon only as varieties by them, and also that 

 the mode of grouping into genera was frequently essentially different." 

 This state of things the author conceives to be the result of the long- 

 continued interruption of scientific intercourse between England and
