Calyx (con)fusion in a hyper-diverse genus: Parallel evolution of unusual flower patterns in Eugenia (Myrtaceae)
Eugenia has a pantropical distribution and comprises ca. 1000 species found mostly in the Neotropics. Recent DNA based phylogenies show that unusual flower morphology of ‘eugenioid’ collections, e.g. fused calices that open by tearing, consistently emerged within Eugenia. These results emphasize a demand to revaluate flower morphology in a phylogenetic...Giaretta, Augusto ; Vasconcelos, Thais ; Mazine, Fiorella Fernanda ; Faria, Jair Eustáquio Quintino ; Flores, Rodolfo …

Taxonomic monograph of Eugenia sect. Schizocalomyrtus (Myrtaceae: Myrteae), a group within Eugenia with unusual flowers.
Taxonomic monograph of Eugenia sect. Schizocalomyrtus, supported by molecular and morphological evidence, is presented. The flowers of this section have unusual fused calyces that are contrasted with standard Eugenia flowers with free calyx lobes. Because the fused calyx recurs in Myrtaceae and has been historically misleading for taxonomists, a key...Giaretta, Augusto ; Lucas, Eve ; Sano, Paulo Takeo

Phylogenetic Relationships Within the Hyper-Diverse Genus Eugenia (Myrtaceae: Myrteae) Based on Target Enrichment Sequencing.
is one of the most taxonomically challenging lineages of flowering plants, in which morphological delimitation has changed over the last few years resulting from recent phylogenetic study based on molecular data. Efforts, until now, have been limited to Sanger sequencing of mostly plastid markers. These phylogenetic studies indicate 11 clades...Giaretta, Augusto ; Murphy, Bruce ; Maurin, Olivier ; Mazine, Fiorella F. ; Sano, Paulo …

Polysporangiate anthers described in Eugenia (Myrtaceae) with notes on evolutionary patterns.
Shifts towards compartmentalisation resulting in multilocular anthers have been described in some families of Myrtales but to date, not in Myrtaceae. In these other families sporogeneous tissue is partitioned by transverse or longitudinal septa, fitting the definition of the ‘polysporangiate anther’. Polysporangiate anther in Eugenia, a Neotropical genus of Myrtaceae...
