Genus Ostryopsis refers to a group of deciduous trees commonly known as Asian hazels or hop-hornbeams. They are similar in appearance to true hazels, but are distinguished by their hop-like fruits and hornbeam-like leaves. In taxonomy, synonyms for Genus Ostryopsis include Betulaster, Betulopsis, and Crocanthemopsis. They are native to Asia, with some species being found in countries such as China, Japan, and Korea. The wood of these trees is used for a variety of purposes, such as fuel, construction, and furniture-making. While not as well-known as their true hazel counterparts, Genus Ostryopsis trees make a beautiful addition to any landscape.
