260 Notices and Analyses. 



The Map of Piauhy is a precious document for the geography of South 

 America, and would, perhaps, have been more vahiable, had MM. 

 Spix and Martins, instead of publishing the great map of this con- 

 tinent, only given to the world their own particular labours during 

 their stay in Brazil. These materials would have enriched the 

 geography of this continent, and would have been considered as 

 positive data, whilst their great map is but an incomplete work. 

 . The first attempt at a map of these countries is attributed to Father 

 Henrique Antonio Galluzi. He must have determined, in 1761, 

 the latitude of the Capital, and of all the towns of the Capitania, as 

 well as some longitudes. Two other editions were afterwards com- 

 pleted, and upon these the map of which we are now speaking is 

 founded. 



These maps were enlarged and corrected by MM. Spix and Martins, 

 after some original designs, some itineraries of the environs of Rio 

 de San Francisco, and memoirs in the Portugese Journal, O 

 Patriota. 



The two last sheets, that is to say, the Sections and the Map of 

 Vegetation, form part of the great atlas of MM. Spix and Martins, 

 which is joined to the description of their travels in Brazil. 



Flora der Phanerogamischen Geio<Bchsen^ &;c. Flora of the 

 Phaenogamous Plants of the Environs of Leipsic. By Klett 

 and RiCHTER ; with a preface by Professor Reichenbach. 

 Leipzig. Hofmeister. 



Many works have been published on the Flora of Leipsic ; they are, 

 however, very far from presenting a complete view of the vegetable 

 riches of the neighbourhood of this city ; and the authors of this 

 Flora have done a service to botanists, in collecting all the materials 

 to perfect their work. M. Klett died in 1827, and M. Richter now 

 continues the publication of the work alone. M. Schwsegrichen 

 having proposed to publish shortly a topographical description of 

 Leipsic, in relation to its Natural History, M. Richter has not 

 introduced this department into his work. The whole is written in 

 German ; and though valuable, as are all local floras, it is not of 

 much immediate interest to the English botanist. 



Synopsis Hydrangece generis specierum Japonicarum ; Auct, 

 SiEBOLD. Nov. Act. Acad. Nat. Car. Tom. xiv. p. 686. 



M. Nees Von Esenbeck, the editor of this memoir, mentions in a 

 note, that the author had announced a complete work, accompanied 

 with figures, on the species of Hydrangea ; but that, with a fatality 

 which seemed to attend all works published on the natural history 

 of Japan, these descriptions had not yet arrived in Europe. To 

 neglect nothing, however, which might be serviceable to botanists, 

 he had given this Synopsis, where the characters of the genus and 

 species of Hydrangea are stated in a concise way. 



A dissertation on the genus Hydrangea has been published by M. 

 Courtois, in the Sylloge Plantarum of Ratisbon, IL 38, in which the 

 American species have been particularly examined, and the description 

 of the fruit given by M. Nees Von Esenbeck. The memoir of 

 M. Siebold is devoted to the Japanese species, which are nine in 

 number : H. hortensia, H. Azizai, H. japonica, H. Thunbergii, 

 H. viridis, H. paniculata, H. involucrata, H. alternifolia, and H. 

 sitsitan. The author gives a specific character for each of these, 

 with the Japanese and Chinese synonymy, written in Roman, 

 Japanese, and Chinese characters.
