Phylogenetic reconstruction in Myrtaceae using mat K, with particular reference to the position of Psiloxylon and Heteropyxis

Parsimony analysis of matK sequence data for representatives of Myrtaceae s.1. provides evidence of its potential in phylogenetic inference in this family. Psiloxylon and Heteropyxis comprise a robust clade, basal to representatives of Myrtaceae s. str., and strongly clustered with it. In a limited sample of Myitaceae s. str., several strongly supported groups are identified: the myrtoid genera (excluding Syzygium), representatives of the Chamelaucium alliance, and the Chamelaucium plus Leptospennum alliances.
