Genera

The Calycanthaceae (sweetshrubs or spicebushes) are a small family of flowering plants in the order Laurales. The family contains three genera and only 10 known species [3], restricted to warm temperate and tropical regions:

Calycanthaceae

Calycanthus (three species; western and southeastern North America and one species in eastern Asia)

Chimonanthus (six species; eastern Asia)

Idiospermum (one species; Queensland, Australia)

[citation needed]

They are aromatic, deciduous shrubs growing to 2–4 m tall, except for Idiospermum, which is a large evergreen tree. The flowers are white to red, with spirally arranged tepals. DNA-based phylogenies indicate the Northern Hemisphere Calycanthus and Chimonanthus diverged from each other in the mid-Miocene, while the Australian Idiospermum had already diverged by the Upper Cretaceous and likely represents a remnant of a former Gondwanan distribution of Calycanthaceae.

The oldest definitive fossil of the family is Jerseyanthus from the Turonian of New Jersey; the even earlier Araipa of Brazil and Virginianthus from Virginia may also represent members of the family, but may also be stem-Calycanthaceae or more basal Laurales.[1]

In the APG IV system of 2016, Calycanthaceae is placed in the Laurales order in the magnoliids clade.[4]
