Betulaceae, family Betulaceae, birch family(noun)
monoecious trees and shrubs (including the genera Betula and Alnus and Carpinus and Corylus and Ostrya and Ostryopsis)
The birch family, Betulaceae, includes six genera of deciduous nut-bearing trees and shrubs, including the birches, alders, hazels, hornbeams and hop-hornbeams, numbering about 130 species. They are mostly natives of the temperate Northern Hemisphere, with a few species reaching the Southern Hemisphere in the Andes in South America. In the past, the family was often divided into two families, Betulaceae and Corylaceae. Recent treatments, including the Angiosperm Phylogeny Group, have described these two groups as subfamilies within an expanded Betulaceae--Betuloideae and Coryloideae. The closest relatives of Betulaceae are believed to be the Casuarinaceae, or the she-oaks.
