OLEACEAE 



Green Ash 



Praxinus pennsylvanica lanceolata, (Bofkli.} Scirg. [Fraxinus 

 lanceolata, Borkh.] [Fraxinus viridis, Michx. /.] 



Considered by some authors to be a distinct species, and by 

 others a variety of F. pennsylvanica, Marsh., which it resembles. 

 The main points of difference are : 



The usual absence of pubescence from the branchlets, 

 the under side of the leaflets, and the petioles. 



The rather narrower, shorter, and more sharply 

 serrate leaflets. 



The color of the leaves, which is bright green on both 

 sides. 



A very hardy tree, of rapid growth and desirable habit, mak- 

 ing it useful for ornamental and street planting. Easily trans- 

 planted. 



Of rare occurrence in Michigan, but has been reported from 

 several localities.
