It is a great choice for any product that needs wood that is strong and resistant to damage, wear and tear.
Plant habit and lifestyle: Plants Angiosperms, monoecious, 20–40 m tall
Stems: Moderately stout and pale brown in color, fuzzy (particularly when young); leaf scars large and three lobed. Twigs tan to reddish brown, thin, hairy, quite scaly, sometimes becoming glabrous. Bark light brownish-gray and shaggy. Thin fissures divide the bark into scaly, interlacing ridges.
Buds: Terminal buds yellowish brown to brown in color, scaly and hairy. Shape oblong, 6-12 mm; bud scales valvate; axillary buds protected by bracteoles fused into hood.
Leaves: Alternately arranged, deciduous, pinnately compound with leaflets (7-)9-13(-17), lateral petiolules 0-7 mm, terminal petiolules 5-25 mm; blades ovate-lanceolate, often falcate, 2-16 × 1-7 cm. Single or double serrated leaf margins without tufts of hairs, apex acuminate; surfaces abaxially hairy or with scattered unicellular and 2-rayed fasciculate hairs, scaly with large peltate scales and small round peltate scales, adaxially without hairs or rarely hairy with unicellular hairs along midrib, and with scattered 2-6-rayed fasciculate hairs. Leaf midribs are off-center, giving the leaflets a sickle shape.
Flowers: Flowering takes place from April through May. Wind pollinated. Flowers staminate and pistillate. Both on the same tree. Staminate flowers appear in slender fascicled, sessile catkins, 8 - 15 cm (3 - 6 in) long. Pistillate catkins are hairy, yellow, and not as many as staminate ones, with two to four stigmas The calix is two- or three-lobed, with a center lobe that is longer than the lateral ones, and five or six stamens.
Fruits: Nuts about 1 2.6–6 cm long and 1.5–3 cm broad, elliptical or pear-shaped. Fruit maturation 1-3 years
Habitat: Rich, moist, well-drained soils, often in river bottomlands. Needs a humid climate and rich loamy soil.
Special Diagnostic Characteristics: Fruits are enclosed in husks developed from the floral involucre. Husk is thin, dark brown about 1/4" thick. Flowers are yellowish in color. Pointed tips and leaf bases of leaflets are often unequally rounded or wedge-shaped. Leaf upper surface dark, yellowish-green in color. Leaf lower surface pale.
