Ostrya virginiana, the American hophornbeam, is a species of Ostrya native to eastern North America, from Nova Scotia west to southern Manitoba and eastern Wyoming, southeast to northern Florida and southwest to eastern Texas.
American hophornbeam is a small deciduous understory tree growing to 18 m (59 ft) tall and 20–50 centimetres (8–20 in) trunk diameter. The bark is brown to gray-brown, with narrow shaggy plates flaking off, while younger twigs and branches are smoother and gray, with small lenticels. Very young twigs are sparsely fuzzy to thickly hairy; the hairs (trichomes) drop off by the next year.
The leaves are ovoid-acute, 5–13 cm (2–5 in) long and 4–6 cm (1 1⁄2–2 1⁄4 in) broad, pinnately veined, with a doubly serrated margin. The upper surface is mostly hairless, while the lower surface is sparsely to moderately fuzzy (rarely densely hairy).[
