The anatomy of fruit development and its evolution in the Myrteae tribe (Myrtaceae)

Nayara Carreira Machado, Maria Luiza Dias Piassa, Karinne Sampaio Valdemarin, Daiane Aparecida Camargo Portella et autres

• We found that the development pattern of the pericarp layers is a diagnostic character for the sections within Myrciinae. • Selected characters are strong taxonomic and phylogenetic indicators, particularly: • The presence of secretory cavities in the mesophyll/external mesocarp is the …

Floral anatomy of 12 species of the subtribe Myrciinae (Myrteae, Myrtaceae)

Isabele Pierin Carneiro, Marcela Thadeo, Káthia Socorro Mathias Mourão

Abstract Myrciinae, one of the nine subtribes of Myrteae, is a monophyletic group and only includes Myrcia. Phylogenetic studies have culminated in the establishment of sections in this genus supported by floral morphological traits. The anatomy of reproductive organs in Myrteae has …
