Reassessment of family alignments in the Myrtales assigns subfamilial
status to three, or possibly four, monogeneric families (Sonneratiacea
e, Dunbangaceae, Punicaceae, and perhaps Trapaceae). Three subfamily n
ames, previously used but not validly published, are validated. The ba
sis for validation is summarised for all five subfamily names that are
of potential use in phylogenetically based classifications of the Lyt
hraceae.
