The main purpose of this study was to test the hypothesis that Stachys persepolitana is extraneous in Stachys (tribe Stachydeae, subfam. Lamioideae, Lamiaceae) and instead belongs to the genus Lamium (Lamieae, Lamioideae). We investigated the phylogenetic position of S. persepolitana using plastid (rps16 intron, trnL-F and matK regions) and nuclear (nrITS) DNA sequence data with both parsimony and Bayesian phylogenetic approaches. Plastid and nuclear data strongly support that S. persepolitana is extraneous in Stachys and belongs in fact to the genus Lamium. Morphological characters also corroborate its placement in Lamium. Most of the morphological features used to distinguish S. persepolitana from the rest of Stachys fit with Lamium. Anterior pair of stamens bending outward after pollination, anthers hairy and mericarps triquetrous are the most important characters correlating S. persepolitana to Lamium.

Poaceae Family

Phylogenetic relationships of the whole Poaceae family inferred from the sequence data of rDNA (ITS) support the hypothesis that the arundinoids are monophyletic, not polyphyletic as previously proposed. The ITS sequence phylogeny of 42 arundinoid species demonstrates an early divergence of the Aristideae and three major groupings, corresponding loosely to the tribes Aristideae, Arundineae and Danthonieae. The Arundineae are resolved into two paraphyletic clades. In one clade, Arundo, Monachather, and Dregeochloa are the sister group to Amphipogon and Diplopogon. In the other clade, Phragmites, Molinia, Gynerium, Thysanolaena, Spartochloa, and Cyperochloa are the sister group to Eriachne and Micraira. Arundo is not closely related to Phragmites. The Danthonieae clade, including taxa from Africa, Australia, New Guinea, New Zealand, the South American Cortaderia, and the North American Danthonia, appears to be monophyletic. However, the genus Merxmuellera is polyphyletic.

Genus Eucalyptus

This expanded survey of ITS sequences represents the largest analysis of molecular data ever attempted on Eucalyptus. Sequences of the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA were included in an analysis of 90 species of Eucalyptus s.s. and 28 species representing eight other genera (Allosyncarpia, Angophora, Arillastrum, Corymbia, Eucalyptopsis, Stockwellia, Lophostemon and Metrosideros). The results of the study indicate that Angophora and Corymbia form a well-supported clade that is highly differentiated from Eucalyptus s.s. Corymbia species are divided between two clades, one of which may be the sister to Angophora. Allosyncarpia, Arillastrum, Eucalyptopsis and ‘Stockwellia’ are also highly differentiated from Eucalyptus s.s. If the genus Eucalyptus is to be expanded to include Angophora and Corymbia(sensu Brooker 2000), ITS data suggest that Allosyncarpia, Eucalyptopsis, ‘Stockwellia’ and potentially Arillastrum should also be included in Eucalyptus s.l. The ITS data suggest that subg. Symphyomyrtus is paraphyletic and that subg. Minutifructus should be included within it. Within subg.Symphyomyrtus, only sect. Maidenaria appears to be monophyletic. Sections Adnataria and Dumaria are probably monophyletic; sections Exsertaria and Latoangulatae are very close and probably should be combined in a single section. Section Bisectae is polyphyletic and is divided into two distinct lineages. The phylogenetic groups depicted by ITS data are consistent with the frequency of natural inter-specific hybridisations as well as data from controlled crosses within subgenus Symphyomyrtus. The ITS data illustrate that subg. Idiogenes and western Australian monocalypts are early evolutionary lines relative to E. diversifolia, E. rubiginosa (monotypic subg. Primitiva) and the eastern monocalypts and that subg. Primitiva should be sunk into subg. Eucalyptus. Subgenus Eudesmia may be monophyletic, grouping with subgenera Idiogenes and Eucalyptus. Further work is required to confirm the phylogenetic positions of the monotypic subgenera Alveolata, Cruciformes, Acerosae and Cuboidea.
