A large tree 70 — 80 feet in height, and 2 — 4 in diameter. Leaves alter- 
nate on petioles 2—3 inches long, palmately lobed, and cordate, the lobes 
acuminate and serrate, when young sprinkled with a few hairs; when old, 
hairy only in the axils of the leaves. Sterile ament terminating the small 
branches, ovate, composed of globular heads. Stamens numerous. Fertile 
ament globular near the base of the sterile. Calyx glandular. Gems nu- 
merous. Styles 2, thick. Stigmas obtuse. (Ament at length ligneous and 
alveolate, capsules by pairs inserted in the alveoli, 1-celled, 1-valved, follicu- 
late, internally lined with collateral rows of angular scrobiform deciduous 
bodies, applied to the few winged and perfect seeds, Nuttall.) 
The leaves of this tree when bruised are fragrant, and it exudes a gum 
which is pleasant and slightly aromattrr *It^wnod , ’teSPys Farpfrily when ex- 
posed to the weather; and though fine grained and adapted to some of the 
uses of the Carpenter and Cabinet-Maker, it is yet but little employed. 
Grows every where in wet and damp soils. Attains its greatest size in 
our river swamps.
