 The genus lies in the subtribe Embothriinae, along with the tree waratahs ("Alloxylon") from eastern Australia and New Caledonia, and "Oreocallis" and Chilean firetree ("Embothrium coccineum") from South America.Almost all these species have red terminal flowers, and hence the subtribe's origin and floral appearance must predate the splitting of Gondwana into Australia, Antarctica, and South America over 60 million years ago.
