Tree Acorns for Oak Tree Identification.

Oak is the most common name for trees listed in the genus Quercus. There are a few species that exhibit a shrub type growth form instead of a tree form. There are both deciduous and evergreen species and some are semi-evergreen. Currently there are approximately 600 different species listed in the Quercus (Oak) genus. The tree name "Oak" is also used for the common names of some species in related genera, especially those listed in the Lithocarpus genus.

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 Oak tree is well known for its reproductive fruit, a nut called an "Acorn", that develops in a cup like structure, a "Cupule". Each acorn contains one seed (rarely two or three) and takes 6 to 18 months to mature, depending on the species. The flowers are catkins, produced in the spring. Oaks have spirally arranged leaves, with a lobed margin in many species; some have serrated leaves or entire leaves with a smooth margin.

Some evergreen Oak trees (especially certain American Species) are given a grouping common name called "Live Oak". 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. Thus, evergreen Oaks (Live Oaks) can be considered to be a type of Oak tree, only as far as that they are an evergreen type of Oak. Evergreen Oaks (Live Oaks) are identified by the % symbol in the list below.
