central New York and southward, and may be distinguished 

 by its fruits. In Darlington's ash the wings of the fruit are 

 narrow, and practically parallel-sided, while in the red ash 

 the wings are broader above the middle, the sides of the wing 

 converge downward, and they are not parallel. 



Michaux's Ash Fraxinus Michauxii 



As yet this tree is little known and its distribution not fully 

 determined. It is known to grow from southern New York 

 to North Carolina and specimens grow in the grounds of 

 New York Botanical Garden, at Closter, New Jersey, and 

 on Staten Island. Its general features resemble the red 

 ash and its chief distinctive characteristics are the greater 

 thickness of its leaflets and the greater width of the fruit. 

 Their margins are practically smooth while in the red ash 

 the margins of the leaflet are more or less toothed, except in 

 rare instances. 



White Ash Fraxinus Americana 



Probably the best known and one of the most widely 

 distributed of our native ashes. The tree prefers rich hill- 

 sides and in such situations often reaches a height of 120 

 feet. Its bark is thick, grayish-brown and irregularly 

 fissured. 



There may be from 5 to 9, usually 7, leaflets composing 

 the compound leaf and each leaflet is distinctly stalked. They 

 are sharp-pointed at the tip, rounded or acutish at the base, 

 from 3 to 6 inches long and fine toothed or smooth on the 

 margins. The under face of the leaflet is paler than the 

 upper and is either hairy or quite smooth. As in the red ash 

 the fertile and infertile flowers are, in the majority of cases, 

 borne on different trees. Sometimes, however, both kinds 

 of flowers may be found on the same tree, but in different 

 flower-clusters. The fruits are winged above and the 

 margins of the wing are either parallel or converge slightly 

 downward. The seed-bearing part of the fruit is full and 

 round, the wing arising from its upper end, and not running 

 down the side of the seed.
