rapidly disappearing from the southwestern part of the State. 

 The light and coarse-grained wood is valueless, but the bark is 

 somewhat largely used medicinally. Rocky hillsides, more often 

 along streams and rich river bottoms.

PTELEA L. 



P. trifoliata L. Hop tree. Shrubby Trefoil. 



Commonly distributed throughout the State, usually in shady 

 localities. Frequent on shady, rocky hillsides. A small tree, 

 ranging from twelve to fifteen feet in height and with a diameter 

 of from six to nine inches. In many parts of the State the species 

 occurs as a shrub. The foliage leaves have an unpleasant odor 

 when bruised; the bitter fruit is sometimes used as a substitute 

 for hops.

SIMARUBACE^E. Ailantbus Family. 

 AIL\NTHUS Desf. 



A. glandulosa Desf. Tree of Heaver). 



Escaped from cultivation very largely in some of the southern 

 counties. I have seen whole hillsides completely covered with 

 this species. It spreads especially in a coarse, rocky soil. The 

 foliage has a fetid, disagreeable odor when bruised, and the 

 staminate flowers are especially ill-scented. 



Flowers in June and July.

 rion (Wilson); Fayette (Hessler).
