1 88 Trees with Compound Leaves. [DI 



A large, showy tree (sixty to seventy feet high) of 

 remarkably vigorous and rapid growth. It is a native of 

 China. A Jesuit missionary sent its seeds in 1751 to 

 England. In 1784 it was brought from Europe to the 

 United States, and started near Philadelphia. Also 

 about 1804 it was brought to Rhode Island from South 

 America. But the source of most of the trees now found 

 abundantly in the region of New York is Flushing, Long 

 Island, where it was introduced in 1820. It has been a 

 great favorite, and would deserve to be so still were it 

 not for the peculiar and disagreeable odor of its flowers.
