In woods rare. 



Tree. April, May. 



Leaves for the most part simple, 4 or 5 inches long, strongly but 

 unequally serrated, on long footstalks. A few other leaves are 

 said to be three-lobed, or ternate ; or even pinnate of 5 leaflets. 

 Seed elliptical, shorter than in F. excelsior ; of which, neverthe- 

 less, I suspect this to be a mere variety.
