Laurales

The Laurales are an order of flowering plants. They are magnoliids, related to the Magnoliales.

The order includes about 2500-2800 species from 85-90 genera, which comprise seven families of trees and shrubs. Most of the species are tropical and subtropical, though a few genera reach the temperate zone. The best known species in this order are those of the Lauraceae (for example bay laurel, cinnamon, avocado, and Sassafras), and the ornamental shrub Calycanthus of the Calycanthaceae.

The earliest lauraceous fossils are from to the early Cretaceous. It is possible that the ancient origin of this order is one of the reasons for its highly diverged morphology. Indeed, presently no single morphological property is known, which would unify all the members of Laurales. The presently accepted classification is based on molecular and genetic analysis.

Under the older Cronquist system, the Laurales included a slightly different set of families (current placement, where different, in brackets):
