Corylus cornuta
（重定向自Beaked hazelnut）
Corylus cornuta (Beaked Hazel) is a deciduous shrubby hazel found in most of North America, from southern Canada south to Georgia and California. It grows in dry woodlands and forest edges and can reach 4–8 metres (13–26 ft) tall with stems 10–25 centimetres (3.9–9.8 in) thick with smooth gray bark. The leaves are rounded oval, coarsely double-toothed, 5–11 centimetres (2.0–4.3 in) long and 3–8 centimetres (1.2–3.1 in) broad, with hairy undersides. The flowers are catkins that form in the fall and pollinate in the following spring.
