I. — Marti us on the Botany of Brazil. 



It is well known to our readers that the most accomplished 

 of all Brazilian Botanists, Dr Von Martius, besides the valu- 

 able and splendid works 'of plates and descriptive matter 

 which have already appeared, or are in course of prepara- 

 tion, has issued Fasciculi oi dried specimens illustrative of the 

 Flora of that extensive region, under the title of Herbarium 

 FlorcB Brasiliensis. The Introduction to the catalogue of 

 plants in this herbarium contains so much valuable and in- 

 teresting information, that we think we cannot do belter than 

 occupy some of the pages of our Journal with extracts from 

 the original memoir which has appeared in a German perio- 

 dical publication, too little known in this country, the Flora 

 Oder Allgemeine Botanische Zeituvg; in the supplement of the 

 2d volume for the year 1837. We shall, probably, on a 

 future occasion, publish also the list of the species contained 

 in the herbarium, accompanied as it is by remarks which are 

 of the greatest importance to the student of Brazilian Botany.

Dr Martius commences his introductory observations by 

 saying, that in publishing the first part of his Catalogue Rai- 

 sonee of the plants of Brazil, he considers it necessary to offer 

 some remarks : — 1st. On the botanical collections that had 

 been made, and the travels that had been performed by his 

 predecessors. 2dly. On the geographical distribution of the 

 vegetable forms ; and 3dly. On the plan the author has him- 

 self pursued in determining the plants of Brazil, and in the 

 formation of the herbarium of the Flora of Brazil.
