Urbanodendron is a genus of flowering plants in the family Lauraceae. The three species are native to Brazil.
Little information is available about the genus because the species are rare and endangered.
These are evergreen monoecious trees with alternately arranged leaves. The flowers have six tepals and nine stamens. [1]
These are endemic species of the Brazilian tropical seasonal semi-deciduous montane forests, the cloud forest. In 1978, after five centuries of occupation and the effects of various economic cycles, the Brazilian Atlantic Forest, has been reduced to about only 7.6% of its original extension, in a drastic deforestation.

There are three species: [1]
The flowering plant family Lauraceae, the laurels, includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as Sassafras, are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus Cassytha is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous.
