|name = Asian hazel |image=Corylus heterophylla.JPG |genus = Corylus |species = heterophylla |authority = Fisch. ex Trautv. }}Corylus heterophylla, the Asian hazel, is a species of hazel native to eastern Asia in northern and central China, Korea, Japan, and southeastern Siberia.[1] It is a deciduous shrub or small tree growing to {{convert|7|m|ft|abbr=on}} tall, with stems up to {{convert|20|cm|0|abbr=on}} thick grey bark. The leaves are rounded, {{convert|4|–|13|cm|frac=4|abbr=on}} long and {{convert|2.5|–|10|cm|0|abbr=on}} broad, with a coarsely double-serrated to somewhat lobed margin and an often truncated apex. The flowers are wind-pollinated catkins; the male (pollen) catkins are pale yellow, {{convert|4|cm|frac=4|abbr=on}} long, while the female catkins are bright red and only {{convert|1|–|3|mm|frac=16|abbr=on}} long. The fruit is a nut produced in clusters of 2–6 together; each nut is {{convert|0.7|–|1.5|cm|frac=4|abbr=on}} diameter, partly enclosed in a {{convert|1.5|–|2.5|cm|frac=4|abbr=on}} long, bract-like involucre (husk).[1][2] It is very similar to the closely related common hazel (C. avellana) of Europe and western Asia, differing in the leaves being somewhat more lobed.[2] UsesThe nut is edible, and is very similar to the common hazel nut; it is cultivated commercially in China.[1] References1. ^1 2 Flora of China: Corylus heterophylla {{Nuts}}{{commons category}}{{Taxonbar|from=Q976000}}2. ^1 Bean, W.
