When isolated it develops a, rounded ovoid top, which may be recognized w-hen leafless by its stout straight branclilets (those of the stami- nate tree being larger than of the pistillate) and the gray scaly bark of trunk. It inhabits the low banks of streams and cold swamps, in company witli the Arbor-Vita!, Balsam, Tamarack, Silver Maple, Black Spruce, etc., sometimes forming a considerable portion of forest tracts. Its wood is rather heavy, a cubic foot when dry weighing 38.,37 lbs., moderately hard and strong, and is valued in the manufacture of furniture and lumber for interior finishing, for barrel hoops, etc. It is extensively used in the manufacture of splints for baskets, owing to the facility with which it splits between the layers of annual growth. The "Ash Burl" veneering is a product of this tree, being sliced from the " knots " or burls which form on its trunk and larger branches.

Flowrra polygamo-dioecious, calyx none ; petals none: stamens 2 sometimes rudimentary in the pistillate flowers.
