Manual of British Botany, containing the Flowering Plants and Feims 

 arranged according to the Natural Orders. By Charles Cardale 

 Babington, M.A., F.L.S. &c. 2nd edit. 12mo, pp. 428. Van 

 Voorst, London, 1847. 



In studying the species of British plants, it is of great importance to 

 have a book which contains short and at the same time accurate dis- 

 criminating descriptions, and one which can be easily taken to the 

 fields for the purpose of consultation. Mr. Babington's ' Manual ' 

 combines these requirements. The work is portable, the characters 

 of the species are given with great care from personal observation, 

 and the names have been revised so as to make the nomenclature 

 correspond as much as possible with that adopted by the best bota- 

 nists in Europe. " It has been the author's wish to adopt in all cases 

 those names which have the claim of priority, unless good cause 

 could be shown for a contrary proceeding ; and with this object he 

 has carefully examined nearly all the best European Floras, com- 

 paring our plants with the descriptions contained in them, and in 

 very many cases with foreign specimens of undoubted authenticity. 

 In the adoption of genera and species an endeavour has been made, 

 by the examination of the plants themselves, to determine what are 

 to be considered as truly distinct ; thus, it is hoped, taking nature 

 as a guide, and not depending upon the authority of any name how- 

 ever distinguished." 



The work is founded in some measure on the model of Koch's 

 ' Synopsis Florae Germanica?,' and undoubtedly is the best Manual 

 of British Botany which we possess. It is not a compilation, but an 

 original work embracing the results of the author's examination of 

 the species in most cases in their native localities. In giving the 

 characters, the essential and distinguishing points are put in italics, 

 thus calling the attention of the student at a single glance to the 

 marked differences of the species. The natural system of DeCan- 

 dolle is adopted with some modifications, and the Linnsean system is 

 used as a key to the genera. In this way the work may be said to
