A small tree. Leaves opposite, unequally pinnate. Leaflets oval-lan- 
ceolate, acute, finely but acutely serrate, paler underneath, veins prominent, 
pubescent when young, on petioles 2 — 3 lines long. Wing of the fruit broad, 
lanceolate, slightly emarginate at the summit, extending from the base of the 
seed. 
Michaux says that this tree rarely exceeds 30 feet in height. I think 
it sometimes becomes a large tree. I have seen, however, as he remarks, 
young shoots (probably from old roots) not exceeding ten feet in height, 
bearing flowers and fruit in great profusion. 
Grows in deep swamps. / 
Flowers March.
