Considerações sobre a distribuição e morfologia de Tovomita calophyllophylla García-Villacorta & Hammel (Clusiaceae) no Brasil

Abstract

Considerations on the distribution and morphology of Tovomita calophyllophylla García-Villacorta & Hammel (Clusiaceae) in Brazil). In the last years taxonomic reviews and local floras about the Clusiaceae family have exponentially advanced the taxonomic knowledge of the group. As a result of these recent discoveries, several new species and the extension of the distribution range of taxa have been published. Here, we provide the first field photos of the flowers and fruits, as well as the first description of the staminate flowers of Tovomita calophyllophylla García-Villacorta & Hammel. Moreover, we expanded the species geographic range for the Center-west region of Brazil. Description, comments on the distribution and taxonomy, and an identification key of Tovomita species occurring in the Center-west region are provided.

“…Later, in another worldwide study, Marine phylogeographic studies in Brazil, using macroalgae as model organisms or otherwise, hypothesize the influence of distinct processes acting as barriers to gene flow along the Brazilian coast, such as: (1) estuaries or the mouth of major rivers such as the Doce river, the São Francisco river, and the Amazon river (Floeter et al 2008 the southern Brazil Bight separating a tropical from a subtropical marine climate zone (Horta et al 2001); and (8) the Cassino Beach, the longest stretch of sandy beaches in the southern hemisphere, located between latitudes 32º S and 34º S . A plethora of studies are still needed to determine how these processes have driven 63 macroalgaeand other marine speciesgenetic diversity, structuring, differentiation and speciation along the Brazilian coast.…”
