16 MARTIUS ON THE BOTANY OF BRAZIL. 



Enumeratio Filicum, quas in itinere circa terram legit Adalb. 

 de Chamisso, auct. T. F. Kaulfuss, Lips, 1824, and particu- 

 larly in a valuable series of treatises by Messrs Chamisso and 

 Schlechtendal in the Linnaea, under the title, " De Plantis 

 in expeditione speculatoria Romanzoffiana collectis." 



Freycinet in his "Voyages autour da Monde, 1817-1820," 

 gives, in the botanical portion of Gaudichaud, Paris, 1825, 

 many plants collected at Rio de Janeiro. The second French 

 expedition of Duperrey (1822-1824,) by the botanical la- 

 bours of D'Urville, Brongniart and Bory de St Vincent 

 (Paris, 1828, &c.) has enriched the Flora of Brazil with 

 plants that have been gathered at St Catharine. Other 

 French Naturalists, as Gay and Leschenault, landed also at 

 Rio de Janeiro, and sent their collections to the Herbarium 

 of the Museum in the Jardin des Plantes. M. Gaudichaud 

 also enriched this Museum with some thousand specimens of 

 plants which had been procured by various Brazilian collec- 

 tors, and placed in the public Cabinet at Rio de Janeiro. O. 

 Von Kotzebue also visited Rio again during his voyage round 

 the World, in the years 1823-1826. Professor William 

 Jamieson (now of the University of Quito,) collected Mosses, 

 which have been described by Dr Arnott. 



It must, nevertheless, be confessed, that it is not by hasty 

 visits of Naturalists that the general Flora of the country could 

 be made known to us, but by those Europeans, who have 

 penetrated into the interior, and who had so long been ex- 

 cluded from it. The first who thus collected plants in Bra- 

 zil, was a German, Mr Sieber. Para, at that time, under 

 the presidency of the enlightened Conde dos Arcos, enjoyed 

 a happy peace. Count von HofFmanseg, so well known by 

 his travels in Portugal, and his illustrated Flora of that coun- 

 try, sent his servant Sieber to Brazil, in order to collect in- 

 sects, and he brought to his patron a considerable collection 

 of dried plants, some gathered in the environs of Para, others 

 in Cameta, along the banks of the Toeantins. Many of 

 these were given by Count HofFmanseg to Willdenow for 

 his Species Plantarum. But the collection was described by
