banks of streams :" and Tucuman is described as " chiefly pastoral, 

 but more hilly, with cultivation carried on in its valleys." 



146. The EXTENSIVE unwooded plains of Northern Brazil. From 

 Pernambuco Westward, and including the Sertain, Goyaz, and Matto 

 Grosso. Described as almost entirely pastoral, " wooded only upon 

 the banks of the rivers." 



147. The Catinga district op Central Brazil. Interposed on the 

 head-waters of the San Francisco, Tocantines, and Parana proper ; 

 and described as " extensive and somewhat elevated open plains, with 

 frequent hollows and narrow valleys where the trees become more 

 flourishing and form matted woods." The foliage of these woods is 

 further described as periodically deciduous; a winter of drought serv- 

 ing the same purpose here as a winter of cold in the North. 



148. The Forest Region of Southern Brazil. An unbroken forest 

 along the Atlantic from Bahia to St. Catherine's, or from S. lat. 13° 

 to a little beyond S. lat. 27°, and extending over the whole range of 

 the Organ Mountains, but not much farther inland. In richness and 

 variety of vegetable productions, exceeding any other part of the globe 

 I have visited. 



149. The two ocean Islets of Trinidad and Martin Yas. Situa- 

 ted in the Atlantic, to the Eastward of Rio Janeiro. Possibly aflbrd- 

 ing a trace of a distinct botanical region. 



150 ? The OCEAN Islet of Fernando Noronha. Situated in the 

 Atlantic, not far from the Equator. The geographical position indi- 

 cates the possible presence of a peculiar species of plant : the islet, 

 however, may be too small to afford any vegetable growth.
