Types of Oak Trees: They are Just So Pleasant to See

Types of oak trees
Today, there are nearly 400 species of oak trees that exist around the world. They can grow in a variety of habitats ranging from wet lowlands to high dry mesas and from seacoasts to high mountain slopes.
Oak trees may be either deciduous or evergreen and are widespread in the North Temperate Zone. Around springtime, before the new leaves appear, the tree flowers due to the large quantity of pollen that is shed into the wind. Oak trees have clustered flowers and are identified by their distinctive fruit, the acorn, which has a cup-like structure called a 'cupule'. Depending upon which species they belong to, trees may have spirally arranged leaves with a lobed margin, serrated leaves or entire leaves with a smooth margin.
