Ostrya carpinifolia is found in Lebanon, Italy, France, Austria, Slovenia, Albania, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, Greece, Bulgaria, southern Switzerland and Turkey. It is found in the medium elevations, in southern Italy and Sicily, in the South Apennine mixed montane forests ecoregion of the Mediterranean forests, woodlands, and scrub Biome.
Ostrya carpinifolia is a broadleaf deciduous tree, that can reach up to 24 metres (79 ft). It has a conical or irregular crown and a scaly, rough bark, and alternate and double-toothed birch-like leaves 3–10 cm long.
The flowers are produced in spring, with male catkins 5–10 cm (2–4 in) long and female catkins 2–5 cm (3⁄4–2 in) long. The fruit form in pendulous clusters 3–8 cm (1+1⁄4–3+1⁄4 in) long with 6–20 seeds; each seed is a small nut 2–4 mm (1⁄16–3⁄16 in) long, fully enclosed in a bladder-like involucre.
The wood is very heavy and hard, and was historically used to fashion plane soles.
Ostrya are used as food plants by the larvae of some Lepidoptera species.
