The order in which Polygonoideae tribes are shown here has been modified somewhat from Reveal's system, based on phylogenic data shown in Schuster et al. (2013) "Age Estimates for the Buckwheat Family Polygonaceae Based on Sequence Data Calibrated by Fossils and with a Focus on the Amphi-Pacific Muehlenbeckia.
