Knowra Platanus Platanus Platanus is a genus of large deciduous trees native to the Northern Hemisphere. Its species have distinctive mottled bark and spherical fruiting heads.
Platanaceae : Platanaceae is a small family of flowering plants whose living members belong to the genus Platanus. This family is the taxonomic level immediately above plane trees.
Deciduousness : Deciduousness is the seasonal shedding of leaves, usually before an unfavorable season. Plane trees drop their broad leaves in autumn or during dry seasonal conditions.
Urban forestry : Urban forestry is the management of trees and wooded spaces in towns and cities. Plane trees are widely planted as long-lived shade trees along streets and in parks.
California sycamore : Platanus racemosa, the California sycamore, is a plane tree native to California and Baja California. It represents the genus’s distinctive western North American lineage.
Platanus occidentalis : Platanus occidentalis, the American sycamore, is a plane tree native to eastern North America. It is a widespread North American species in this genus.
Pollination : Pollination is the transfer of pollen to the receptive part of a flower, enabling fertilization. Plane trees produce separate male and female flower heads that are chiefly wind-pollinated.
Street tree : A street tree is a tree planted along a road or in its associated public space. Plane trees tolerate many urban conditions and form broad, shady canopies.
Arizona sycamore : Platanus wrightii, the Arizona sycamore, is a plane tree native to the southwestern United States and northern Mexico. Its range illustrates how some plane trees thrive in seasonally dry regions.
Platanus orientalis : Platanus orientalis, the Oriental plane, is a plane tree native to southeastern Europe and western Asia. It is a major Eurasian species in the genus.
Achenes : Achenes are small, dry, one-seeded fruits that do not open at maturity. Each spherical plane-tree fruiting head consists of many densely packed achenes.
