Which older plant order once included several families that are now placed in Ericales?

The older plant order that once included several families now placed within the Ericales is the now-defunct order Theales.1

While the current classification of Ericales is well-supported by morphological and molecular data, its circumscription represents a significant shift from earlier, morphology-based classification systems, such as the one developed by Arthur Cronquist. Under the modern APG IV system, Ericales is recognized as a basal asterid order containing 22 families.12
