The circumscription of the Fabroniaceae is revisited based on phylogenetic inferences from published rps4 (cpDNA) and nad5 (mtDNA) sequences. Only Ischyrodon forms a clade with Fabronia, a relationship defined by the wavy-walled exothecial cells as a possible synapomorphy. The genus Levierella is nested within the Entodontaceae, Dimerodontium among taxa traditionally associated with Leskeaceae and the position of Rhizofabronia is uncertain.
