NOTE ON THE DESCRIPTIVE LIST OF FLOWERING 



PLANTS. 



For the convenience of botanists this part aims to gather in one gen- 

 eral list the descriptions of the Patagonian Flora which are scattered over 

 many books. Extreme condensation is required by the limitations of 

 space ; and as we deem a natural serial arrangement of species an impos- 

 sibility, we have placed the species of each genus in alphabetical order, 

 which facilitates reference. In order to minimize the labor of identifica- 

 tion, all the larger genera are provided with an artificial key to the spe- 

 cies, whereby any plant may be paralleled with its congeners, and its 

 name provisionally obtained for comparison with its diagnosis in the 

 ensuing alphabetical arrangement. 



The arrangement and diagnoses of the families and genera are in 

 accord with Engler and Prantl's Pflanzenfamilien, with occasional* help 

 from the writings of Bentham, Gray, Britton and others. Immediately 

 after the descriptive list we give an analysis of the Alliances and Families 

 of the Flowering Plants of the area; this follows the method of Engler 

 and Prantl, as modified by Coulter and Chamberlain.
