Crataegus × smithiana, or perhaps more correctly Crataegus 'Smithiana', is a hybrid hawthorn commonly known as red Mexican hawthorn. The hybrid is said to have originated at the Yarralumla Nursery in Canberra, Australia.[1] This tree has been planted along several streets in Canberra.
The Latin binomial that is sometimes used, Crataegus × smithiana or the equivalent C. smithiana, appears to have never been validly published[2] under the rules of the International Code of Botanical Nomenclature.
