Previous morphological taxonomic studies suggested that this genus is closely related to the western South American Minthostachys. Phylogenetic analyses of nucleotide sequences of the internal transcribed spacers and 5.8S subunit of nuclear ribosomal DNA and the trnL gene and trnL-trnF spacer of the chloroplast genome for 33 of the 72 genera in the Mentheae tribe were performed. Maximum parsimony analysis of the combined data set resulted in 63 most parsimonious trees. The strict consensus tree of this analysis shows with moderate bootstrap support (74\%) that Bystropogon is sister to the Old World taxa Acinos, Ziziphora, and Clinopodium vulgare. When analyzed separately, the ITS and trnL/F data sets do not agree as to the sister group to Bystropogon, although none supports a sister relationship with Minthostachys. The cpDNA phylogeny strongly supports a relationship of Bystropogon with a clade of New World mint taxa (90\% bootstrap value). Due to the apparent conflict between the chloroplast and nuclear characters observed in the phylogenies, we are not certain of the true biogeographic relationship of Bystropogon. Finally, in all analyses, all of the Mentheae genera sampled in this study form a monophyletic group (100\% bootstrap value) and a derived clade of ten New World genera is found. These results contribute to our understanding of generic relationships within the tribe.}, keywords = {Canary-Islands, Chloroplast Dna, Ilex L.

Rev. Ecol. Syst. 23:449-480), with emphasis on nomenclatural stability and efficiency. Comparison of published cladistic analyses revealed 19 suprageneric clades within Lamiaceae that are supported well enough to merit naming, but many genera could not be placed with confidence in any infrafamilial taxon. Two phylogenetic classifications were prepared, one following current nomenclatural rules and conventions and the other following the phylogenetic system of nomenclature. A comparison of the classificationsrevealed examples of unstable and ambiguous names that resulted from employing current rules and conventions to name clades. Old names based on nomenclatural types of uncertain phylogenetic relationship and infrafamilial taxon names based on the type of the family are particularly prone to instability. The phylogenetic system appears to have fewer problems but may also lead to nomenclatural confusion if taxon names are defined carelessly. The current system produces less efficient classifications because the principle of exhaustive subsidiary taxa leads to inclusion of redundant names (monotypic taxa) when the classification is based on an asymmetrical cladogram. In contrast, the phylogenetic system contains no redundant names. We endorse the recommendation that the principle of exhaustive subsidiary taxa be abandoned. Phylogenetic definitions should be provided for taxon names whenever phylogenies are translated into classifications. The definitions should be accompanied by a list of synapomorphiesand a statementof clade membership to facilitate subsequent provisional referral of newly studied species to supraspecific taxa.}, author = {PD CANTINO and RG OLMSTEAD and SJ WAGSTAFF} } @article {WAGSTAFF:1998p1141, title = {Phylogeny in Labiatae sl, inferred from cpDNA sequences}, journal = {Plant Systematics and Evolution}, volume = {209}, number = {3-4}, year = {1998}, month = {Jan}, pages = {265{\textendash}274}, abstract = {Sequences of rbcL and ndhF were analysed independently and in combination to resolve phylogenetic relationships in Labiatae s. 1.
