TO SUBSCRIBERS. 



The present Number, containing the engravings of only two plants, 

 renders it proper to state, that the table of Centaurea Americana, being 

 a folio plate, cost the publishers exactly the same sum as two quarto 

 plates, both in engraving and colouring, and consequently is equivalent 

 to the two quarto in lieu of which it stands. It will occasionally be 

 expedient to follow this plan in figuring very large plants, which, with- 

 out reduction in size, could not be brought into the quarto dimensions: 

 and as it is customary in the European Botanical works to substitute 

 a large plate, instead of two smaller ones, where the beauty, size, or 

 novelty of the plant may render such a plan desirable — the subscribers 

 for this Flora, will not. it is hoped, disapprove of a similar arrangement.
