 ceolatCy acuminate, obscurely serrate, strotigly veined, almost fibbed, very 

 glabrous. Flowers in small axillary panicles. Stamens much longer than 

 the rudiments of the corolla. The fruit in panicles composed of small clus- 

 ters, terete at base, extending from the summit a very long narrow wing, 

 slightly emarginate at the summit.

A tree 50^ — 70 feet high, and sometimes 2 — 3 feet in diameter. Leaves 

 opposite, and as in all of the American species of the genus unequally pin- 

 nate. Leaflets^ 3—4 pair, oval-lanceolate, acuminate, generally entire, glab- 

 rous nndcraeath. Fruit somewhat terete at base, with a long lanceolate 

 wing extending from the centre. 



The wood of this species, under the name of Whhe Ash, is said by Mi* 

 chaux to be employed in preference to that of the other species of this genus. 

 I believe, however, they are all indiscriminately used. Their wood is light, 

 elastic, and sufficiently strong, and is much used by Carriage-Makers, 

 Wheelwrights, and Cabinet-Makers. 



Grows as most if not all of the genus, in rich swamp or bottom land> 



Flowers March. '
