the older enumerations of Swartz and Willdenow, as may still remain 
obscure; and also such as may assist in the recognition of the new un- 
figured species of later writers. 
** While adopting the modern system of classification, which was first 
generally applied with so much sagacity by Presl, and has since been 
modified by the accurate and useful labours of Mr. J. Smith and M. Fée, 
a considerable amount of close investigation has led the author to the 
conclusion that the genera have been too much multiplied, and it will. 
be his object to consolidate what appear to be unnecessary subdivisions. 
'There can be no doubt, moreover, that species have been too much mul- 
tiplied, but the difficulties of accurately consolidating these false species 
without vast materials for comparison, is so great, that he fears he may 
not accomplish in this department so much as he desires. Any ma- 
terials in aid of this object, will, however, be thankfully appreciated.— 
For facility of reference, the genera and species in the body of the work 
will be arranged in alphabetical order.— Those botanists who may be 
disposed to render aid in this undertaking, by the communication of 
specimens, are invited to forward them to the author, under cover to 
the publisher."
