Notes: Notes It is not clear if this variety should be transferred to the genus Planchonella or remain in Pouteria. It is here maintained within the genus Pouteria until the relationship between these two genera is resolved. However, it is expected that this taxon will probably be transferred to the genus Planchonella.
