tion of Phanerogams" (being a refutation of the hypothesis proposed 

 by Schacht, after Kadlkofer had demonstrated the groundlessness of 

 his and Schleiden's opinion on the subject). Caspary, " On the De- 

 velopment of Heat in the Flowers of Victoria regia and other Plants" 

 (the most elaborate treatise that has ever appeared on these pheno- 

 mena) ; there are also all the articles that have hitherto appeared in 

 various periodicals and transactions, on the much-discussed JEgilops 

 question, together with several original ones by Hegel in St. Petersburg, 

 aud Klotzsch in Berlin. 



Of systematic papers we have a great many of permanent value. 

 We would draw particular attention to those of Reichenbach, fil., on 

 Orchidece, scattered throughout the four volumes that have hitherto 

 appeared, — in which we find more than 500 Orchidea (the collections 

 of Schlim, Warszewicz, Wagener, Sartorius, Hance, Euiz and Pavon, 

 etc.), carefully described, constituting one of the most valuable contri- 

 butions to that branch of botany ; Miquel's " Synopsis of the Aralia- 

 cece of Dutch India," Liebmann's "New Mexican Oaks," Seemann's 

 " Review of the genus Tancecium" Schlotthauber's u Enumeration of 

 the Broseracece and Utricularice of South-western Australia," Kornike's 

 "Botanical Sketch of Calumet, Wisconsin, United States" (with a 

 synopsis of all the plants of that district, and a review of the genus 

 Jgrimonid). Besides these articles, and others too numerous to men- 

 tion, there are also translations of important articles from foreign pe- 

 riodicals, among which we quote as an illustration, Bentham's famous 

 review of the Loganiacea, lately published in c The Journal of the Pro- 

 ceedings of the Linnean Society of London,' reviews of new works, 

 miscellaneous notices (original and selected), and all the botanical news, 

 derived both from original sources, and all other periodicals devoted to 

 botany. 



Every number opens with a leader on some prominent topic of the 

 day, always written with great fairness and impartiality, further secured 

 to the interested parties by a part of the paper set aside for the sole 

 purpose of giving every one an opportunity of pleading his own cause, 

 without the least restriction on the part of the editors. Most of the 

 articles of the 'Bonplandia' are in German, the systematic articles in 



Latin; but communications made in other languages are also admitted, 

 as we find several English and French inserted. 



On the 15th of January, 1857, the < Bonplandia* commenced its
