“…2022 Three species of Myrcia sect. Aguava occur in the VNR, a group represented by 32 species throughout the distribution of genus (Lucas et al 2011;Lima et al 2021). This section is recognised in the study site by the combination of leaves with inconspicuous reticulation and flowers with thin staminal ring and 3-locular ovaries.…”

Myrcia (Myrteae, Myrtaceae) is represented by 101 species in the Brazilian state of Espírito Santo, but local floristic surveys on this genus still lack in this centre of diversity and endemism. In this context, a taxonomic account of Myrcia in the Vale Natural Reserve (VNR), Linhares, Espírito Santo, is presented. Forty-six species were registered in this study, representing 46% of the richness of the genus in Espírito Santo. Twenty-five species (54%) are endemic to the Atlantic domain and seven are endemic to Espírito Santo. Myrcia scytophylla is reported in the Atlantic forest for the first time and M. cymatophylla, M. congestiflora, and M. ferruginosa are new occurrences in the state. Species composition revealed by this study considerably differs from that of a previous checklist. Representatives of Myrcia can be found in all main vegetation types of the VNR and the anthropic areas. The study site must be considered prioritary for conservation of Myrcia due to the presence of a rich assemblage, which also includes restrict and threatened species.

Lophostemon confertus (Myrtaceae), a fast-growing ornamental tree, is widely cultivated in tropical and subtropical regions. To determine its phylogenetic position within Myrtaceae, here we report its complete chloroplast (cp) genome, which is 160,297 bp long and contains two inverted repeats (IRs) of 26,490 bp each, separated by a small single-copy region of 18,826 bp and a large single-copy region of 88,491 bp. The cp genome contains 123 genes, including 73 unique protein-coding genes (six duplicated in the IR regions), 29 unique tRNA genes (seven duplicated in the IR regions), and four unique rRNA genes (all located in the IR regions). Phylogenetic analysis of 18 species of Myrtaceae showed that L. confertus is sister to Xanthostemon chrysanthus. The complete cp genome of L. confertus provides a valuable genetic resource for further phylogenetic studies.

“…Over time, many dispersal events occurred from the Amazon toward the Cerrado, and from the Amazon towards the Atlantic Forest; certainly, the Amazon was an important source of lineages to surrounding areas (Antonelli et al 2018). On the other hand, the Amazon and the Atlantic Forest have both received lineages from the Cerrado (Aguiar et al 2019;Gonçalves et al 2020;Lima et al 2021), but in a lower frequency. Dated molecular phylogenies and biogeographic analyses provided evidence that dispersal events were frequently associated with habitat shifts from forest and savanna or vice-versa.…”

The tree genus Dimorphandra comprises 26 species, which are circumscribed into three subgenera. The subgenus Dimorphandra is associated with both rainforests (Amazon and Atlantic Forest) and savanna-like vegetation (Cerrado); whereas the subgenera Pocillum and Phaneropsia are restricted to the Amazon. We obtained DNA sequence data from six gene regions of the chloroplast genome (cpDNA) and the nuclear internal transcribed spacer (ITS) from 17 species of Dimorphandra and 12 closely related species. Bayesian phylogeny and haplotype network analyses together with both ancestral area reconstructions and ecological niche modeling allowed for exploring the late evolutionary history of the genus Dimorphandra. Species within the subgenus Phaneropsia were more closely related to species of the genus Mora than to the remaining congeners in the plastid tree (but not in the ITS tree), casting doubts on the monophyly of Dimorphandra. Such incongruence may be the result of incomplete lineage sorting of ancient polymorphisms. Amazonian lineages (subgenera Pocillum and Phaneropsia) were highly polymorphic and divergent; whereas lineages from either the Cerrado or the Atlantic Forest were genetically depauperate. The Amazon seems to be the likely source of the lineage that gave rise to the extant species of Dimorphandra of the Cerrado. In turn, a lineage that occupied the Cerrado likely gave rise to the extant species that occur in the Atlantic Forest. Habitat shifts may have been a key driving force that shaped the late evolutionary history of Dimorphandra.
