An oak is a tree or shrub in the genus Quercus Latin "oak tree"), of which about 400 species exist. "Oak" may also appear in the names of species in related genera, notably Lithocarpus. The genus is native to the northern hemisphere, and includes deciduous and evergreen species extending from cold latitudes to tropical Asia and theAmericas. Oaks have spirally arranged leaves, with a lobed margin In many species; some have serrated leaves or entire leaves with a smooth margin. The flowers are catkins, produced in spring. The fruit is a nut called an acorn, borne in a cup-like structure known as a cupule, each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on species.
