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...

We provide a description and illustration of Mollinedia lorencei , sp. nov. The species exhibits morphological similarities and is compared to both M. lamprophylla and M. dolichotricha . Furthermore, we provide comments on the taxonomy, ecology, geographic distribution and conservation status of this new species.

Mollinedia (Monimiaceae) presents numerous microendemic species, and its centre of diversity is in the Brazilian Atlantic rainforest, where more than half of the species occur. The taxonomy of microendemic species can be challenging because their morphological and genetic variations can be interpreted as a response to geographic isolation rather th...

The present study is part of the Flora of Espírito Santo project and aimed to survey and describe the morphological diversity of species of Bixaceae from Espírito Santo state, Brazil, as well as to provide data on geographical distribution, biology, and habitat of these species. To do so, fieldwork was carried out in several areas of Espírito Santo...

Amazonia, despite being famous as the most prominent tropical forest, is currently suffering high rates of degradation, with recurrent fires and deforestation, which could shortly lead it to be classified as a biodiversity hotspot for conservation. Although the known flora of the domain displays exceptional richness, its diversity is far from being...

Paepalanthus, in its current sense, is the most diverse genus of Eriocaulaceae in the Neotropics, comprising about 400 species. Previous studies have consistently found that the genus is not monophyletic, also being morphologically heterogeneous and diagnosable by a set of homoplasies; thus, the current circumscription needs to be revised. The new...

The genus Utricularia (Lentibulariaceae) is the most diverse and cosmopolitan among carnivorous plants. Utricularia sect. Foliosa sensu Taylor (1989) is composed of three South American species, U. amethystina, U. tricolor and U. tridentata, the first species being recognized as highly diverse.

Paepalanthus is the second largest genus of Eriocaulaceae, with about one-third of the species recorded for the family, but it has not received a recent comprehensive taxonomic treatment. Detailed taxonomic studies show that many names currently in use are actually synonyms. In addition, it was necessary to lectotypify some names. Twenty-five synon...

Leaf venation has not been widely used in taxonomic integrative works, although some potential in delimiting taxa has been reported. Hyptidendron, a neotropical genus with 20 species, seemed to present some variation in leaf venation patterns, which we sought to further investigate. A number of different herbaria were consulted, and herborized leav...

Short Abstract Here we present a reflection based on a long-term research in the Jalapão region (central-Brazil). If our initial interest was to understand local perceptions about the Brazilian Savanna's biodiversity, with time we have evolved our focus to a knowledge co-production perspective. The case studies were made through qualitative and com...
