NEW SYLVA OF NORTH AMERICA. 



Or the New and revised Trees, Shrubs 

 and Vines observed, collected, and ascertain- 

 ed or corrected between 1802 and 1836, by 

 C. S. Rafinesque Jc : all figured in my Au-

The Trees and Shrubs .of North America 

 have received very early attention, because 

 they could usually be cultivated in Europe in 

 the open grounds; several were introduced 

 there long ago : Duhamel wrote chiefly upon

 to him. He was followed and improved upon 

 by Castiglione in Italy and Vangenheim in 

 Germany, who both wrote on North American

 ed also many figures of them in their works ; 

 but they were all exceeded by Michaux junior 

 who after publishing the splendid Monograph 

 of American Oaks of his father, printed both in 

 French and English a very good special work 

 on our Trees. 



Watson, Jacquin and others have since pub- 

 lished iconographical dendrologies, and several 

 monographs have appeared ; among which de-

 Muhlenberg, Wildenow, Smith <c, Pines and 

 Firs by Lambert, our Ash trees by Bosc in-

 Roses 1820 increased to 25 species, with my
