Comment on a new classification of the eucalypts

Brooker's classification of the eucalypts, which combines Angophora, Corymb ia and Eucalyptus into one genus, is contrary to phylogenetic evidence base d on eight different data sets including morphology, RFLPs, and sequence da ta for various regions of nuclear and chloroplast DNA (5S rDNA spacer regio n, ITS1, ITS2, trnL intron, trnL-F spacer and psbA-trnH spacer). On this ev idence and the principle of recognising monophyletic taxa, we reject his sy nonymy of these genera.
