BRAZIL PROVINCE OF MINAS GERAES. 257 



second volume of the Flora, oder AUgemeine Botanische Zeitung 

 for the year 1837 ; and a translation of it has been published by 

 Sir W. Hooker in the fourth volume of his Journal of Botany. 

 Tiie regions which he establishes are five in number, viz. : — 



1. Regio Extra-Tropica, — This region includes all that 

 plain or gently undulating country extending between the south- 

 ern tropic and Monte- Video. The northern parts of it are the 

 highest, and the mountains there are covered with forests, some 

 of which consist entirely of the Araucaria Braziliensis. Further 

 south the country becomes lower, and the forests more rare, and 

 mingled with the American are to be found European forms of 

 vegetation. To the plants of this region Martins gives the name 

 of NapcecE. 



2. Regio Montano-Campestris. — This region includes the 

 great Brazilian mountain system, which constitutes the interior 

 of the province of Minas Geraes to the west, as also part of the 

 provinces of Rio de Janeiro, San Paulo, Goj^az, Matto Grosso, 

 and Bahia. The vegetation of this region is that which I have 

 described as existing on the SerradoDuro, and the Serra Geral, 

 in the province of Bahia, and that of the mountains in the Gold 

 and Diamond districts. To the plants peculiar to this region 

 Martins gives the name of Orcades. 



3. Regio Montano-Nemorosa. — This region includes the 

 mountain forest tracts. To it especially belongs the Cordillera 

 of the coast, called Serro do Mar, extending from the j)rovince 

 of Sail Paulo to Bahia, and northerly from it to the other side 

 of the Rio de Sari Francisco, in the provinces of Alagoas 

 and Pernambuco. The southern flora of this region is somewhat 

 different from tliat of the north on account of the greater height 

 of the mountains and more humid atmosphere ; but they have, 

 notwithstanding, in their physiognomy, corresponding forms. 

 This of course includes the Organ Mountains, as well as tlie 

 other mountains in the province of Rio, the vegetation of which 

 is distinguished above all others by greater magnificence in form 

 and colour. This region passes into the Extra-tropical one on 

 the south, to the Montano-campestris on the west, and in the 

 north merges into the Catinga forests of the northern provinces. 

 To the plants of this region is given the name of Drijades. 



4. Regio Calibo-Sicca. — This region includes all those 

 tracts of country which in Brazil are called by the name of 

 sertad, which literally signifies desert. It is the most thinly 

 inhabited, and embraces that part of the province of Minas which 

 lies between the mountains of the Gold and Diamond districts 

 and the Rio de Sail Francisco, as well as part of that which ex- 

 tends up to tlie Serra Geral towards Goyaz. It likewi.se includes 

 the interior of the province of Bahia, the south-western part of 

 the province of Pernambuco, and the valley of the province of
