Convergent evolution in calyptrate flowers of Syzygieae (Myrtaceae)
Abstract Shedding a fused perianth as a calyptra at anthesis is a trait that has evolved independently multiple times in angiosperm evolutionary history. However, calyptras do not correspond to homologous structures in all cases. Here, we describe calyptra development in the evolutionary context of Myrtaceae tribe Syzygieae. We use scanning...Vasconcelos, Thais N C ; Lucas, Eve J ; Conejero, Maria ; Giaretta, Augusto ; Prenner, Gerhard

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 …
