Ixxvi - PROCEEDINGS OF THE 



Martius's great work on the Brazilian flora, already mentioned iii 

 my previous Addresses (which amounts almost to a series of mono- 

 graphs by various authors), is progressing slowly ; the portions pub- 

 lished' since those I mentioned in 1866 have been : — Meissner's 

 Lauraceae, supplemented by an essay ou the geographical distribu- 

 tion of the order in the Transactions of the E,oyal Munich Academy ; 

 Dr. Hooker's llosacese ; and Eichler's Combretacece. 



Dr. Schweinfurth, of Berlin, has at length published the first part 

 of his ' Contributions to the Flora of ^Ethiopia,' which had, I be- 

 lieve, been long in print, and supplemented it by a monograph of 

 ^Cthiopian Gum-Acacias in the ' Linna^a.' Prof. Alexander Bi-aun 

 has given, in the Proceedings of tho Academy of Berlin, a very 

 detailed monograph of African Characcse. Prom Vienna we have had 

 a splendidly illustrated volume, descriptive of the principal botani- 

 cal results of the spirited, but unfortunate, expedition of the ladies 

 Tinnd to Bahr-Ghasal, and another by Wawra, equally creditable to 

 Austrian art, descriptive of plants collected in the earlier voyage to 

 South America of the late Archduke Maximilian, who afterwards 

 met with so deplorable a fate as Emperor of Mexico. Grisebach, 

 who had previously published detached papers on Wright's Cuban 

 collections, has now given a complete enumeration of all the jjlants 

 known to him, or published as inhabitants of that island ; he has 

 also inserted, in the second volume of ' Das geographische Jahrbuch,' 

 a compreliensive review of the progress of Geographical Botany 

 during the years 1866 and 1867, L. K. Schmarda giving in the same 

 work a similar report on the progress of Geographical Zoology. 



Amongst a considerable number of smaller works and detached 

 papers of mere local botanical interest, I may mention Schur's 

 ' Enumeratio Plantarum Transsylvania3 ' as relating to a part of Eu- 

 rope less known to botanists than Germany proper. Reichenbach's 

 great ' Iconography of the German Flora ' has been steadily pro- 

 gressing, and is now approaching completion. 



The Cryptogamic studies of the Germans have been as numerous 

 as those on physiology ; but I need only here mention Krompel- 

 liubcr's ' Gesohichte uud Littcratur dcr Liclionnlogie,' or ' History 

 and Literature of Lichenology,' forming a comprehensive guide, very 

 useful to those who devote themselves to the study of Lichens ; and 

 Mr. Currey has called my attention to some remarks of De Bary's in 

 the ' Botanische Zeitung,' on Bornet and Thuret's observations, men- 

 tioned below. 



Two elaborate works on the injuries inflicted on trees, chiefly by
