A CARD. 



To THE Purchasers or Holders of the Pro- 



DROMus Flor* Columbians. 



The compiler (Dr. Brereton, U. S. A.) presents his 



due ackiiowleilgements to the above patrons of science, 



•^^ anil informs them, tliat^ after three botanical seasons 



f" The Club" have been iinable^lo add a single plant to ^^ 

 the catalogue; though they have not been remiss in 

 seizing with avidity every occasion aObrded during that 

 time for botanical analysis. 



He, however, excepts, with great pleasure, the acute 

 scrutiny of his friend, \Vm. Mechlin, Essq. a gentleman 

 of very superior attainments, who ha« found three 

 ^)Iants, not contained in the catalogue; two of which 

 are recognized by the compiler, as old accpiaintances; 

 but the third is duly acknowledged a slrangf-r. JJelow 

 are Mr. Mechlin's observaiiDniJ, copied fiom Ins note to 

 the compiler; and they can be easily added to the Pro- 

 dromii:!, which will then be complete. 



'Y\w compiler lakes this occasion to inform theni, ihat^ 

 in the fwUilment of his duties, he will be unjd^Ie.to com- 

 plete the Flora, as therein announced; but he sincerely, 

 hopes, thai a more competent hand will undertake it, 

 who has freely his permission to use the lltuudatioo 

 thus afforded.
