Discussion
Calycanthus occidentalis grows in the northern Coast Range, the southern Cascades Range, and the western Sierra Nevada. It is ecologically similar to C. floridus; it consistently differs from that taxon in a number of vegetative and floral characteristics. Because of an apparent lack of hardiness, C. occidentalis is cultivated less often than C. floridus.
Some American Indians used scraped bark of Calycanthus occidentalis medicinally in treating severe colds (D. E. Moerman 1986).
