SILVA OF NORTH AMERICA. jiagnoliace.t^. 



Magnolia macrophylla was discovered by the elder Michaux in June, 17S9, near Charlotte, North 

 Carolina.' It was introduced into European gardens in 1800 ; but it has never become widely distrib- 

 nted in them or in those of the United States, although few trees equal it in beauty. The flowers and 

 the leaves are the largest of any species of the genus, and they are larger and more conspicuous than 

 those produced by any other tree of the North American forests. Magnolia macrophylla is hardy as 

 far north as eastern Massachusetts. It requires no special care in cultivation, and young plants begin 

 to flower when they are only a few years old. 



1 Michaux, Jour, in Proc. Am. PMLSoc. xxvi. 53,61. In his Flora MIchaus makes no reference to the Carolimi station, and Magnolia 

 macrophylla is credited to the region west of tiic mountains.
