Three new tribes in Myrtaceae and reassessment of Kanieae

The current tribal classification of Myrtaceae was based on analysis the plastid matK coding region within trnK intron. phylogenetic position genera Cloezia and Xanthomyrtus poorly supported, original sequence for Kania, type genus tribe Kanieae, rather poor. To clarify relationships, we sequenced psbA–trnH an extended portion intron, including spacer regions flanking matK, nuclear ribosomal ITS ETS representative species across tribes, denser sampling three interest. Analyses these datasets show a strong relationship between Kania Metrosidereae but not with other presently assigned to Kanieae. is strongly correlated morphological features recently documented in Metrosideros fossils. Consequently, new tribe, Tristaniopsideae PeterG.Wilson, described accommodate most Furthermore, divergence genetic distance shown by are here considered as justifying their recognition tribes Cloezieae Peter G.Wilson Xanthomyrteae G.Wilson. Recognition brings four number absent from present-day mainland Australia. Prior this study, only subfamily Myrtoideae that
