Distribution and habitat Many Lauraceae are aromatic, evergreen trees or shrubs adapted to high rainfall and humidity, but the genus Sassafras is deciduous. Deciduous sassafras trees lose all of their leaves for part of the year, depending on variations in rainfall. In deciduous tropical Lauraceae, leaf loss coincides with the dry season in tropical, subtropical and arid regions.
