Ostryopsis is a small genus of deciduous shrubs belonging to the birch family Betulaceae. The species have no common English name, though Hazel-hornbeam has been suggested, reflecting their similarities to the closely related Hazels and Hop-hornbeams.

The genus is native to China.[1] They are shrubs reaching 3-5 m tall, with alternate, double-toothed hazel-like leaves 2-7 cm long. The flowers are produced in spring, with separate male and female catkins. The fruit form in clusters 3-5 cm long with 6-10 seeds; each seed is a small nut 4-6 mm long, fully enclosed in a sheath-like involucre.[2]

The local people in Northeast China has found hazelnuts of Ostryopsis davidiana and Corylus mandshurica are more delicious than that of Common Hazels and Asian Hazels, and the cuisine "stir-fried huozhenzi" (火榛子) are popular. However, their hazelnuts are far more expensive than common and Asian hazelnuts.
