IT is with much satisfaction that I publish the Index of a 

 work that, after above 23 years labour, is now so nearly 

 completed as only to require now and then an appendix, 

 containing new or previously doubtful plants, to make it a

 from many friends, the mentioniag of whose names adds 

 much value to the work, since it will hand down to poste-

 those that have lived through the period of its | ublication, 

 and to be able to congratulate them upon the fulfilment of 

 the kind hopes they used anxiously to exj>ress, of seeing 

 the close of the work. At the same time, while many others

 indigenous plants of other EuropsBan CouHtries, than tlie resp^ctiye works 

 f aUlished in tiaem.
