calycanthaceae การใช้

• Typical of the Calycanthaceae family, the flowers lack distinct sepals and petals, but instead have distinct spirals of tepals.
• In its 2003 revision, the Angiosperm Phylogeny Group retained it in the new genus, but restored the species to the family Calycanthaceae.
• 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.
• 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.
