More recent research has provided evidence that two of those families, Eremosynaceae and Tribelaceae, arose from within Escalloniaceae; the Angiosperm Phylogeny Website therefore merges these two families into Escalloniaceae, and also places the family alone in order Escalloniales.
Recent research suggests that Eremosynaceae and Tribelaceae are part of the Escalloniaceae family, which is now classified as a single family in the order Escalloniales by the Angiosperm Phylogeny Website.
