“…Aulomyrcia. Two remaining sources of phylogenetic and thus taxonomic uncertainty are firstly, the relationship of species such as Myrcia robusta Sobral (2007: 75) that consistently (Santos 2014;Santos et al 2016;Lima et al in prep. ) emerge in their own clade with poorly supported relationships to other clades.…”

A new classification of the large Neotropical genus Myrcia s.l. is proposed. Nine sections are presented that correspond to recently published clades. Of these nine sections, sects. Myrcia, Aulomyrcia and Sympodiomyrcia are already published, sects. Reticulosae and Tomentosae are new sections, sect. Eugeniopsis is a new combination whilst sects. Aguava, Calyptranthes and Gomidesia are new combinations at a new rank (comb. & stat. nov.). Six lectotypifications are made for sections or genera. Estimates of species per section are listed.

Myrcia s.l. comprises ca. 780 species distributed in nine numbered, informal monophyletic groups. The aims of this work are to improve the phylogenetic and morphological knowledge of one of these clades. The phylogenetic analyses included 24 of the 29 inferred species of "clade 7", plus 80 samples of other clades of Myrcia s.l. and outgroup taxa. Bayesian and maximum likelihood analyses were conducted using the markers ITS, ndhF, psbA‐trnH, trnL‐trnF and trnQ‐rps16. The morphological study employed a maximum‐parsimony algorithm to reconstruct the evolution of selected characters on the Bayesian topology. Myrcia sect. Sympodiomyrcia ("clade 7") is formally described and 28 species are assigned to the group. The new section is defined by the presence of cataphylls, an inflorescence with sympodial basal branching and opposite apical branching, a hypanthium elongated above the ovary and not tearing during anthesis, and calyx lobes free and deciduous. Statistical support for internal relationships is low and there is little congruence with morphology or geographical distribution. A clade corresponding to Calyptranthes appears to be the sister group of Myrcia sect. Sympodiomyrcia and sympodial branching (in vegetative and basal inflorescence branches), presence of cataphylls and deciduous calyx lobes are putative synapomorphies of this clade. Exclusive to Calyptranthes is the calyx with completely fused lobes. Results increase systematic understanding in the large genus Myrcia s.l. but highlight the need for further phylogenetic and morphological studies.

“…Today that proportion is rising as a result of monographic work (e.g. Mazine 2006;Santos 2014) based on clades generated by DNA-based phylogenies (e.g. Mazine 2006;Mazine et al 2014;Lucas et al 2011).…”

Myrtaceae in the Atlantic forest: their role as a ‘model’ group

Myrtaceae is one of the richest families in the Atlantic Forest, a priority biodiversity hotspot that continues to be highly threatened, subject to rapid urbanisation and high levels of resource exploitation. Authors have suggested that individual lineages can be used as models to study biome evolution and ecology and to provide data for conservation planning in these areas. Here we review how Myrtaceae fit the 'model' criteria and examine the family's distribution throughout the Brazilian Atlantic Forest answering the questions: What is the ecological representation of Myrtaceae in the Atlantic Forest?; What is the current taxonomic situation of Myrtaceae in the biome?; What is the current phylogenetic understanding in the family?; Does the historical timeframe of the lineage coincide with that of the biome?; Can Myrtaceae be used to discuss species diversity hotspots within the Atlantic forests?; What is the role of Myrtaceae in conservation strategy? And finally, Can Myrtaceae be used as a 'model' taxon? The concept of the 'model taxon' is also discussed. The review concludes that taxonomic and phlyogenetic understanding in Myrtaceae are rapidly increasing, giving hope that taxonomic stability, easy species identification and management are realistic in a way unthinkable only a few decades ago. Myrtaceae function well as a 'model' within the Atlantic forest but fit some criteria better than others. Taxa can qualify as 'models' representing different times and pressures in the history of a given biome; each tells its own story. For future 'model' group studies to have maximum impact and implementation for evolutionary studies and conservation strategy, synthetic studies of multiple 'model' groups using multiple approaches
