A tree which, in favourable situations, is said by Michaux to attain the 
height of sixty to seventy feet, and a diameter of eighteen to twenty-four 
inches, branches long, virgate. Leaves of the old tree, ovate, acuminate, 
serrate, scabrous on the upper suface pubescent uhderneath; those of the 
young plants frequently palmate and very scabrous. Flowers , I believe, 
always dioecious. Sterile florets in a spike or ament one to two inches 
long, calyx four parted, stamens four, longer than the calyx. Fertile florets 
in a short spike. Calyx four-leaved, after flowering closing becoming juicy, 
forming a cylindrical fruit composed of many one seeded berries. 
Grows in rich alluvial soils, along the margin of rivers and swamps, not 
uncommon though rarely becoming in the low country a large tree. The 
timber is durable and is generally preferred in building boats, or for the light, 
timbers of vessels to any wood excepting the red cedar.
