FRAXINUS PENNSYLVANIA, MARSH. 165 



rusty-velvety or scurfy pubescence lasting often into the 

 second year. 



Winter Buds and Leaves. Buds rounded, dark reddish- 

 brown, more or less downy, smaller than those of the white 

 ash, partially covered by the swollen petiole. Leaves pin- 

 nately compound, opposite, 9-15 inches long ; petiole short, 

 downy, enlarged at base ; leaflets 7-9, opposite, 3-5 inches long, 

 about one half as wide, light green and smooth above, paler 

 and more or less downy beneath ; outline extremely variable, 

 ovate, narrow-oblong, elliptical or sometimes obovate, entire 

 or slightly toothed ; apex acute to acuminate ; base acute or 

 rounded ; leaflet stalks short, grooved, downy ; stipules and 

 stipels none. 



Inflorescence. May. Similar to that of the white ash. 



Fruit. Ripening in early fall, and hanging in clusters 

 into the winter ; samara or key about \\ inches long ; body of 

 the fruit narrowly cylindrical, the edges gradually widening 

 from about the center into linear or spatulate wings, obtuse or 

 rounded at the ends, sometimes mucronate. 



Horticultural Value. - Hardy throughout New England; 

 grows readily in any good soil, but prefers a wet or moist, 

 rich loam ; almost as rapid-growing when young as the white 

 ash, and is not seriously affected by insects or fungous 

 diseases ; worthy of a place in landscape plantations and on 

 streets, but not often found in nurseries ; propagated from 

 seed.
