This name applies to different species that have an evergreen growth habit, and does not reflect any taxonomic classification group, as these species are distantly related in some cases.
Some evergreen Oak trees (especially certain American Species) are given a grouping common name called "Live Oak". 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 the spring. Each acorn contains one seed (rarely two or three) and takes 6 to 18 months to mature, depending on the species. The Oak tree is well known for its reproductive fruit, a nut called an " Acorn", that develops in a cup like structure, a "Cupule". Species of the Quercus ( Oak) genus are native to many woodlands in the Northern hemisphere, from the cold Northern forests to tropical Asian Jungles and Central America. The tree name " Oak" is also used for the common names of some species in related genera, especially those listed in the Lithocarpus genus. Currently there are approximately 600 different species listed in the Quercus ( Oak) genus. There are both deciduous and evergreen species and some are semi-evergreen. There are a few species that exhibit a shrub type growth form instead of a tree form. Oak is the most common name for trees listed in the genus Quercus.
