1. P. TRIFOLIATA, Linnceus. Leaves in 3's. 

 Native of most of the Middle States. 



A small tree, possessing no particular 

 beauty to recommend it. When in fruit it is 

 curious. It has the advantage of thriving in 

 the deepest shade, especially if in a rather 

 moist soil. 



It can be readily propagated by cuttings, 

 layers, or seeds.

 feet high.
