THIS is a tree of low, wet swamps and the borders of rivers, in the Atlantic coastal and Mississippi Valley regions. The seeds are carried far by winds and germinate on wet sandy soils. The tree attains a height of 70 to 90 feet and a diameter of 3 feet. The branches are usually short, forming a narrow, round-topped head, and the buds are SWAMP COTTONWOOD. Twig, three-quarters natural size. Leaf, one-lialf natural size.
. Common forest trees of North Carolina. How to know them. A pocket manual. Trees; Forests and forestry. m''^ â &-m> SWAMP COTTONWOOD {Populus heterophylla L.) THIS is a tree of low, wet swamps and the borders of rivers, in the Atlantic coastal and Mississippi Valley regions. The seeds are carried far by winds and germinate on wet sandy soils. The tree attains a height of 70 to 90 feet and a diameter of 3 feet. The branches are usually short, forming a narrow, round-topped head, and the buds are SWAMP COTTONWOOD. Twig, three-quarters natural size. Leaf, one-lialf natural size. The leaves are broadly ovate, 3 to 6 inches wide and 4 to 7 inches long, gradually narrowed at the tip and slightly rounded toward the base, usually finely toothed along the edges, dark green above, pale and smooth below; on rounded leaf-stems from 2 to 3 inches long. The flowers, which bloom in early spring, are in catkins, the female catkins few-flowered. The fruit, containing the tiny seeds supported by "cotton," is borne on female, or pistillate, trees, and the male, or staminate, flowers occur separately on other trees. The fruit ripens before the leaves are fully grown. The wood is light and soft and, as lumber, re- quires special attention in drying to prevent its warping badly. It makes excellent paper pulp for printing half-tone illustrations. The European white poplar {Populus alha L.) with light-gray bark and leaves, white woolly be- neath, is often found near old houses and along roadsides. The Lombardy poplar, a tall narrow form of the European black poplar (Populus nigra var. italica Du Eoi) is often planted and is a strik- ing tree for the roadside. 26.
