General tree description

Ostrya carpinifolia is a round headed, medium to large tree, up to around 24 metres tall with grey-brown shaggy bark. Its leaves are dark green and glossy above, paler beneath and slightly hairy. They are 8 to 13cm long, ovate, double-toothed and pointed and tapered at the apex. In autumn they turn bright yellow. The yellow-green flowers are produced in spring, with male catkins 5 to 10 cm long and female catkins 2 to 5 cm long. Female flowers develop into fruits, hop-like flat husks 3 to 5cm long, white-greenish in summer, ripening to red-brown, and containing 6mm by 3mm nutlets.
