XXXviii PEOCEBDINGS OV THE 



eeedings of the American Academy, are several illustrative of 

 collections of plants miade in various little-known parts of the 

 North American continent, monographs of American genera, 

 especially of Astragalus, and important notes on E-ubiacese, Com- 

 posite, and other orders not yet publislied in tlie Botany of the 

 American Exploring Expedition. 



Eor the "West Indies, Grrisebacli has completed his Elora of the 

 British possessions, and has since been specially occupied with 

 Cuban plants from American collectors, and has supplemented 

 the enumeration he had published in the Transactions of the 

 American Academy of Sciences by papers in the Gottingen 

 Transactions and Journals. 



For South America, Martins' s great work on Brazilian botany 

 proceeds steadily. Since my last report the principal orders 

 illustrated and described have been, — Scrophulariacese, by J. A. 

 Schmidt ; the several Polypetalous orders commencing the Can- 

 dollean series, by Eichler, who has at the same time supplemented 

 his account of Menispermacese by a separate paper in the Munich 

 Transactions ; Coniferse and allied orders, also by Eichler ; Sapo- 

 tacese, by Miquel ; Eriocaulese, by Kornicke ; Gnetaceae, by 

 Tulasne ; Ericaceae, by Meisner ; Gesneraceae, by Hanstein ; Sal- 

 solacese, by Fenzl ; and Gentianacese, by Progel. 



Planchon and Triana's Flora of New Granada has been com- 

 menced, in detached portions, in the Annales des Sciences Na- 

 turelles. A first portion, comprising the Thalamiflorse, has been 

 reissued in a separate volume. The Ferns (by Mettenius), Sela- 

 ginellas (by A. Braun), Mosses (by Hampe), and Hepaticse (by 

 Gottsche) have since appeared ; and I understand that M. Triana, 

 who is now in this country, has made arrangements with his 

 government by which he will be enabled actively to prosecute his 

 great work at Kew. 



In the above review I have not included the volumijQous con- 

 tributions to Systematic Botany by Baillon and his friends in 

 the ' Adansonia; ' for I was desirous of saying a few words generally 

 upon that work, which is rather a recueil than a periodical. 

 There is no doubt that the papers it contains display a great 

 amount of careful observation, patient investigation, and in- 

 genious views of affinities which cannot be neglected by syste- 

 matic botanists, and that upon Euphorbiaceee especially M. BaiUon 

 has bestowed great pains ; but it must also be admitted that 

 the whole is marred, not only by the irregular mode of 

 publication, but by a frequent neglect of consulting what has
