We have recently received the above contmuations of well-known 

 works, all of which are highly deserving of the attention of British 

 botanists. Dr. Sturm's valuable series of plates of the plants of Ger- 

 many well merits to be better known in this country. These two 

 Parts, which fully support the character for excellence which the 

 work bears, are from the pen and pencil of the son of the original 

 author. 



The 12th volume of Reichenbach's well-known 'Icones' contains 

 the species of ^?we«^ac^<«, Betulacece, Cupuliferce, Urticacece, Aristo- 

 lochiacecB, Laurine(S, Dipsacece and Valerianece. It does not require 

 any recommendation from us, as it is allowed to be essential to all 

 who desire an acquaintance with the European species allied to those 

 of Britain. 



The new fasciculus of the ' Bryologia ' contains a revised account 

 of the PhascacecR, the Archidiacece and Weisiacece, and some supple- 

 mentary plates. 



The receipt of two numbers in continuation of the * Genera Plan- 

 tarum ' of the late Nees von Esenbeck has pleased us greatly, as we, 

 in common probably with most botanists, had feared that the series 

 of misfortunes which have attended the work had brought it abruptly 

 to an end. This is so cheap and so excellent a book that it needs to 

 be seen only to recommend itself, but we may state that these parts 

 are quite equal to their predecessors ; and that Fasc. xxv. contains 

 genera of Dipsacece, Stellatce, Gentianece, and some other orders ; 

 and Fasc. xxvi. is occupied by the first twenty plates of the Umbel- 

 liferce. 



The continuation of the ' Thesaurus ' concludes the alphabetical 

 arrangement of books under their authors' names, and includes the 

 " Opera anonyma." Then commences the " Pars systematica." 



It is highly satisfactory to have so good a proof that the botanical 

 writers of Germany are now again turning their attention to science, 

 having doubtless long been tired of revolution, and that their pixb- 

 lishers also find themselves in a condition to continue the publication 

 of scientific works.
