372 Analysis of Scientific Books and Memoirs. 



which it is besides distinguished by a smaller number of Labiate and 

 Caryophyllece, and by more trees with broad shining leaves, and splendid 

 blossoms {Magnolia, Liriodcndron, JEsculus,) or with pinnate leaves 

 C Gledilschia, Robinia, Acacia, Schrankia, &c.), I have adopted the name 

 of Magnolias, although they are also found in the southern part of the 

 preceding region, because I know not any better. 



VII. ("Regnum Cactorum, Piper acearum, et Melastomearum.) This re- 

 gion I propose should include the lowest districts of Mexico, West In- 

 dies, New Granada, Guinea, and Peru, perhaps also of Brazil. The three 

 families mentioned appear peculiarly to characterize these countries, for 

 the first belongs exclusively to America, the two others possess but few 

 species out of that 'country ; also Palmce, Rubiacew, Solanece, Boraginea, 

 Passijlorece, Composite, are here more common. We may admit of seve- 

 ral provinces ; (a) Provincia Filicum et Orchidearum, comprehends the 

 West Indies ; (b) Provincia Palmarum, the continent of South America. 

 Brazil ought certainly to form a peculiar province, if, indeed, it does not 

 make a distinct region. Melastomcae and Pahnce appear to belong to the 

 more numerous forms. 



VIII. ( Regnum Cinchonarum. ) It appears from Humboldt's works, 

 that the middle districts (with regard to elevation) of South America, 

 should form a distinct region, as they considerably differ from the low 

 lands ; the proposed name seems proper, at least for Peru and New Gra- 

 nada ; but, certainly not for Mexico, where the species of Cinchona arc 

 wanting. 



IX. {Regnum Escalloniarum Vacciniarum et W inter-arum.) In this 

 are placed (also according to Humboldt's works) the highest parts of South 

 America ; besides the plants mentioned, there belong also to this region 

 many species of Lobelia, Genliaiiu, Calceolaria, Salvia, several European 

 Genera of Grasses, Bromus, Fcstuca, Pou, and Cichoiacew, Hypochwris, 

 Apargia ; alpine forms also show themselves, {Saxijraga, Draba, Arena- 

 ria, Cerastium, Carer, and Gentiana.) Perhaps, also, those parts of the 

 high lands of Mexico, where the species of oak and fir flourish, belong to 

 the same region, though, in all probability, they will form a peculiar pro- 

 vince, {Provincia Quercuum et Pinorum.) 



X. {Regnum Chilense.) It appears that Chili may form a distinct 

 region, for, amongst the geiiera which are known from thence, not one-half 

 are found in the low districts of South America ; it has, perhaps, a stronger 

 resemblance to the high lands in the genera Culceolaria, Escallonia, 

 Weinmannia, Baa, Campanula, Budleia, but, however, scarcely sufficient 

 to reduce it to a province. The Flora of this country appears to be essen- 

 tially different from those of New Holland, the Cape, and New Zealand ; 

 though there is found an approach to them in Goodenia, Araucaria, Pro- 

 teacew, Gunnera, Ancistrum.
