Are Callistephus and Epacris native to the same area of the world ?
Epacris Epacris is a genus of about 35–40 species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including "Epacris" have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus "Epacris" is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), New Caledonia and New Zealand. The species are known as heaths or Australian heaths.
Xanthocyparis Xanthocyparis (synonym Callitropsis) is a genus of cypresses in the family Cupressaceae, comprising one species native to North America and one native to Vietnam in southeast Asia.
