The '''Calycanthaceae''' ('''sweetshrubs''' or '''spicebushes''') are a small [[family (biology)|family]] of [[flowering plant]]s in the order [[Laurales]]. The family contains three genera and only 10 known species {{r|Christenhusz-Byng2016}}, restricted to warm temperate and tropical regions:
 
* ''[[Calycanthus]]'' (three species; western and southeastern [[North America]] and one species in eastern [[Asia]])
 
* ''[[Chimonanthus]]'' (six species; eastern [[Asia]])
 
* ''[[Idiospermum]]'' (one species; [[Queensland]], [[Australia]])
 
 
 
They are aromatic, [[deciduous]] [[shrub]]s growing to 2–4 m tall, except for ''Idiospermum'', which is a large [[evergreen]] [[tree]]. The [[flower]]s are white to red, with spirally arranged [[tepal]]s. 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 that included South America, as indicated by the occurrence of Cretaceous Calycanthaceae fossils in Brazil.
 
 
 
In the [[APG IV system]] of 2016 Calycanthaceae are placed in the Magnoliales order in the [[magnoliids]] clade.<ref name="APG4"/>
