BIBLIOGRArHY. 



It is not assumed that the following is a complete record of the literature directly 

 and indirectly bearing on the vegetation of Mexico and Central America, yet if any 

 important contribution to this branch of knowledge is omitted it is through an 

 oversight. The object of it is two-fold, namely to give the full titles and dates of 

 publication of all the books, pamphlets, essays, and articles consulted and utilized, and 

 further to direct attention to sources of greater detail in certain branches of botany 

 than came within the scope of the present work. The abbreviations employed in the 

 Enumeration and elsewhere will, we believe, always be a sufficient guide to the titles 

 here ; therefore we abstain from giving a concordance. Nor has it been thought 

 necessary to cite either publishers' names or places of publication, as such information 

 is easily procured, if wanted, through the leading booksellers. Titles of serials in 

 which the articles referred to appeared are not invariably given in full, as it would 

 occupy space to no useful purpose. On the other hand, we do not pretend to have 

 attained the uniformity of detail met with in special bibliographies. We have attempted 

 a rough classification in which books of a general character appear under the head of 

 the subject to which they contribute most.
