Abstract.Parsimony analysis of matK sequence data from 81 taxa representing 68 genera of Myrtaceae sensu lato, and a representative of each of three related families as outgroups, produced an estimate of the phylogeny of the family with little basal resolution but a number of well-supported clades containing most of the genera. Monophyly of Myrtaceae sensu stricto has moderate support but a broader circumscription, including the small genera Psiloxylon and Heteropyxis that are frequently placed… 

Suprageneric phylogenetics of Myrteae, the generically richest tribe in Myrtaceae (Myrtales)

To clarify relationships within the predominantly Neotropical and exclusively fleshy-fruited Myrteae (49 genera and c. 2,500 species), we provide a phylogenetic hypothesis for evolutionary

Phylogenetics, Morphology, and Evolution of the Large Genus Myrcia s.l. (Myrtaceae)

Phylogenetic relationships of Myrcia s.l., the most species-rich tree genus in the Brazilian cerrado and Atlantic forests, are reconstructed by analysis of four plastid regions and the external and internal transcribed spacer regions of nuclear ribosomal DNA.

Molecular Phylogeny of the Tree‐of‐Heaven Family (Simaroubaceae) Based on Chloroplast and Nuclear Markers

Comparisons among Bayesian analyses reveal that the most complex method of partitioning best explains the data under a Bayes factor criterion, suggesting that the phylogenetic signal is robust and resistant to model misspecification.

Perspectives in Myrtaceae evolution from plastomes and nuclear phylogenies

This phylogenetic estimate offers a contrasting topology over previous analysis with fewer markers about the deep nodes of Myrtaceae phylogeny, and is consistent and reproducible with both nuclear and organellar datasets.

Chloroplast variation is incongruent with classification of the Australian bloodwood eucalypts (genus Corymbia, family Myrtaceae)

There is a need for more focussed studies to assess the extent of hybridisation and introgression in the evolutionary history of these genera, and that critical testing of the classification of Corymbia and Angophora requires additional sequence data from nuclear genomes.

A dated molecular perspective of eucalypt taxonomy, evolution and diversification

This is the first time that a calibrated molecular study has shown support for the rapid diversification of eucalypts in the recent past, most likely driven by changing climate and diverse soil geochemical conditions.

A preliminary phylogenetic analysis of Eugenia (Myrtaceae: Myrteae), with a focus on Neotropical species

Preliminary phylogenetic results presented here combined with morphology point towards the need for a new subgeneric classification for Eugenia, including associated genera and species from Africa and the Pacific.

Morphological and Molecular Evidence of Polyphyly in Rhodomyrtus (Myrtaceae: Myrteae)

Results from morphological and molecular analyses reject the hypothesis that Rhodomyrtus is monophyletic, and additional data are needed before Rhodomarytus can be split confidently into demonstrably monophyletsic genera.

Interpreting the modern distribution of Myrtaceae using a dated molecular phylogeny.

Phylogenetic Relationships in Calyptranthes (Myrtaceae) with Particular Emphasis on Its Monophyly Relative to Myrcia s. l.

The oldest lineages of Calyptranthes are from what is now the Amazon forest, with later radiations to the Caribbean, Atlantic forest, and Cerrado biomes, suggesting wider non-monophyly.



Myrtaceae revisited: a reassessment of infrafamilial groups.

Two separate fleshy-fruited clades, the Acmena and Myrtoid groups, are identified, as are the Eucalypt and Tristania groups, and Psiloxylon and Heteropyxis are the first lineages to diverge in both analyses.

Molecular phylogeny and biogeography of Melaleuca, Callistemon and related genera (Myrtaceae)

To resolve the relationships of taxa within the Beaufortia suballiance (Myrtaceae), 72 ingroup taxa were analysed by parsimony methods and nrDNA sequence data from the 5S and ITS-1 ribosomal DNA spacer regions, showing that Melaleuca is polyphyletic.

A phylogenetic analysis of the Chamelaucium alliance (Myrtaceae)

Analysis of sequence data from the matK gene and the atpβ–rbcL intergenic spacer for 70 representatives of the Chamelaucium alliance sensu Briggs and Johnson (1979) provides strong support for the

Circumscription of Myrtales and their relationships to other rosids: evidence from rbcL sequence data

Parsimony analyses support a sister group relationship between the order Myrtales and a clade formed by an expanded Malvales, Sapindales, and an expanded Capparales.

Phylogeny of Melaleuca, Callistemon, and Related Genera of the Beaufortia Suballiance (Myrtaceae) Based on 5S and ITS-1 Spacer Regions of nrDNA

A phylogenetic analysis of genera within the informal suballiance Beaufortia (family Myrtaceae), largely endemic to Australia and New Caledonia, is presented based on separate and combined data sets

Phylogenetic reconstruction in Myrtaceae using matK, 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

Higher-level relationships among the eucalypts are resolved by ITS-sequence data

The results of the study indicate that Angophora and Corymbia form a well-supported clade that is highly differentiated from Eucalyptus s.s.s and further work is required to confirm the phylogenetic positions of the monotypic subgenera Alveolata, Cruciformes, Acerosae and Cuboidea.

The Genera of American Myrtaceae: An Interim Report

The number of described species is very large, especially in tropical South America, and available herbarium material until recent years consisted chiefly of the classical specimens scattered through European herbaria.

Notes on Myrtaceae in the Mascarenes with Some Recombinations for Taxa from Aldabra, Malaya, New Caledonia

Four genera of Myrtaceae are indigenous to the Mascarenes, Eugenia, Monimiastrum (gen. nov.), Psiloxylon, and Syzygium, and several introduced genera are represented by naturalized species or by commonly cultivated species, such as Callistemon and Eucalyptus.

Proposed new realignments in the angiosperms

Our attempt at putatively phylogenetic classifications of Angiospermae, considering our vast ignorance of more than 120 million years of evolution of the class, must be very tentative and elastic to
