A family of deciduous trees containing the genus Cercidiphyllum, commonly known as katsura trees, native to Asia.
From Cercidiphyllum (the genus name combining Cercis and Greek phyllon 'leaf') plus -aceae, the taxonomic suffix for plant families.
The katsura tree smells like burnt sugar or cotton candy in autumn—it's one of the few trees with fragrant leaves, and scientists had to name an entire plant family around this one strange, wonderful genus.
