Description

Carpinus caroliniana, the American hornbeam, is a small hardwood tree in the genus Carpinus. American hornbeam is also known as blue-beech, ironwood, musclewood and muscle beech. It is native to eastern North America, from Minnesota and southern Ontario east to Maine, and south to eastern Texas and northern Florida. It also grows in Canada (southwest Quebec and southeast Ontario). It occurs naturally in shaded areas with moist soil, particularly near the banks of streams or rivers, and is often a natural constituent understory species of the riverine and maritime forests of eastern temperate North America. American hornbeam is a small tree reaching heights of 10–15 meters (35–50 ft), rarely 20 meters (65 ft), and often has a fluted and crooked trunk. The bark is smooth and greenish-grey, becoming shallowly fissured in all old trees. The leaves are alternate, 3–12 centimeters (1+1⁄4–4+3⁄4 in) long, with prominent veins giving a distinctive corrugated texture, and a serrated margin. The male and female catkins appear in spring at the same time as the leaves. The fruit is a small 7–8-millimeter (9⁄32–5⁄16-inch) long nut, partially surrounded by a three- to seven-pointed leafy involucre 2–3 centimeters (3⁄4–1+1⁄4 in) long; it matures in autumn. The seeds often do not germinate till the spring of the second year after maturating.
