“…Even although the EFNs vary morphologically in Mimosoideae, structural similarity has been observed, even among species of different genera (Lima, Garcia & Sartori, 2007; Morim & Barroso, 2007). The same anatomical arrangement was found in other species, such as Anadenanthera falcata (Benth.)…”

Extrafloral nectaries (EFNs) are found in many species of Fabaceae. The aim of this work is to describe the internal morphology of the EFNs from species of Fabaceae found in areas of dry-seasonal forest in north-eastern Brazil. All species of Fabaceae with EFNs found were collected and samples were submitted to conventional techniques for anatomical and scanning electronic microscopy analysis. EFNs were found in 35 species, of which 32 were examined anatomically. All types have epidermal cells, secretory tissues and vascular bundles in the EFNs. Sclerenchymatous cells were found between the secretory tissues and the vascular tissues, with a few exceptions. The function of these cells is not clear; however, a role in the transportation of the sap in the nectary or with the support of the secretory tissue is possible. The nectar is released through glandular trichomes, secretory pores or even by breaking the epidermal cells and cuticle. The internal patterns found in the EFNs from different species and genera can provide important information for taxonomic and evolutionary studies in the family.

“…A total of 16 floristic studies from the Iron Quadrangle appeared in our search, which were conducted at the following locations: Serra do Ouro Branco (Santos & Sano 2012;Longhi-Wagner & Araújo 2014;Vieira & Barros 2017), Pico do Itacolomi (Dutra et al 2005;Lima et al 2007;Dutra et al 2008a;Dutra et al 2008b;Rolim & Salino 2008;Casarino et al 2009;Dutra et al 2009;Lima et al 2010;Coser et al 2010;Bünger et al 2012;Almeida et al 2014), Serra da Caraça (Morais & Lombardi 2006) and Serra do Rola-Moça (Guarçoni et al 2010). Together, these studies highlight the diversity of plants in this region, reinforcing the need of conservation actions.…”

What is being published on floristics? an overview of floristic studies carried out in the Espinhaço Range

The campo rupestre in the Espinhaço Range is subject of many floristic studies due to its high rates of species diversity and endemism. These studies are made up of critical, easily accessible data about local richness and biodiversity, which are essential for subsidizing new studies in the fields of conservation, ecology, and systematics. This study describes the results of a survey of floristic studies carried out in the Espinhaço Range and provides a checklist of the plant species listed in them. We found that 294 floristic studies were conducted in the Espinhaço Range, but they were focused only on a few areas. Likewise, we detected sampling gaps in some areas. The Floras studied provide information on 3,191 plants or 6,3% Brazilian flora, of which 2,879 are angiosperms, 247 bryophytes, and 65 lycophytes and ferns. Finally, we observed a lack of standardization regarding the habits reported for angiosperms shrubs and subshrubs which is more problematic for Espinhaço's flora because of its grasslands or shrublands vegetation. Thereby, we reaffirm the importance and need to encourage new floristic studies in the Espinhaço Range as a means to train new taxonomists and to provide new studies and projects.
