The impacts caused on Chaco plant communities by the removal of woody species, together with the effects on the composition and functional structure of herbaceous plants, are still unknown. Therefore, this study aimed to assess the effects of anthropization on herb-subshrub communities in preserved and disturbed Chaco areas. Specifically, we examined differences and similarities in species diversity, composition and proportion of life forms in eight areas of Brazilian Chaco. Samples were taken from herb-subshrub communities using 800 1x1m² plots located in disturbed and preserved areas. Among 130 recorded species, 46 were exclusive to disturbed areas. The composition of species differed between preserved and disturbed areas (PERMANOVA; p = 0.001). PCoA ordination analysis showed greater aggregation of the plots in disturbed areas than in preserved areas. In preserved areas, an analysis of indicator species showed Hemicryptophytes species as the most representative life form. In disturbed areas, the proportion of life forms among indicator species was Hemicryptophytes, followed by Therophytes and Chamaephytes. Our study shows evidence that alterations in species composition, structure, and diversity, as well as sets of indicator species, occur in herb-subshrub communities. The removal of trees and bushes leads to a new configuration of this component in Chaco environments.

The Quadrilátero Ferrífero (Iron Quadrangle [IQ]), in Minas Gerais, Brazil, exhibits high geological and geomorphological diversity, reflected by its high heterogeneity of vegetation. Its rock outcrops, particularly ironstone, harbor endemic-rich plant communities and contribute substantially to the biodiversity of the biomes they are embedded within the Atlantic Rainforest and Cerrado region. The aim of this study was determining the distribution, phenology and state of conservation of one new species for science with occurrence in the Quadrilátero Ferrífero. Random walks were carried out in the areas of potential occurrence of the species and individuals were collected to allow description. The plant species was identified and categorized as being new to science and known only from this location: Agalinis marianae (Orobanchaceae). This new species is morphologically similar to A. itambensis but can be recognized by the smaller pedicels and the shape of the corolla. The distinct geographic distribution of these species is an additional factor that supports this separation. Here, we describe and illustrate A. marianae , and provide notes on its distribution, habitat, phenology, and conservation status. We also present a key to the species of Agalinis from Minas Gerais.

The need for grassland restoration in the State of Rio Grande do Sul (RS), Brazil, has become evident in the last two decades, when more than 1 million hectares were converted to other uses only in the Pampa region. Since then, studies have started to verify the most suitable ways to restore subtropical grasslands. Around the world, species introduction is one of the principal restoration techniques. We investigated the availability of seedlings and seeds of native grassland species in the local market and the legal framework regarding the restoration of grassland vegetation in RS. We found, in total, only seven companies that sold seedlings or seeds of nine native species from grasslands, a very limited number given the great biodiversity of South Brazilian grasslands. In addition to that, we found no criteria and procedures for grassland conversion or obligatory replacement established in legal norms for grasslands to Pampa region, as there are for forest vegetation. Without legal requirement, a market for seeds and seedlings likely will not develop and, without a market, there will be no producers, and restoration will remain limited. Our results support the need to create initiates and legislation with basic guidelines for the grassland conversion and restoration in RS.

During fieldwork in Serra Negra da Mantiqueira, Minas Gerais state, southeastern Brazil, a new taxon of Passiflora , subgenus Astrophea , was collected in cloud forest areas. Passiflora purii , the new species, is characterized by the conical trochlea and the totally vinaceous corona, and was named in honor of the Puri ethnic group that inhabited the mountain range where its population was located. Detailed data on the distribution, habitat, reproductive phenology, and conservation status of the new species, as well as a key to closely related taxa of subgenus Astrophea are provided

High-Altitude Fields are ecosystems with high bryophyte abundances and diversities. One of the principal threats to these ecosystems are wildfires, which mainly affect terricolous species. Chronosequence studies can aid in understanding post-fire effects on bryophytes. We studied terricolous assemblages of bryophytes in the High-Altitude Fields of Itatiaia National Park (INP) by establishing three 20x1 m transects in five areas: three areas of a post-fire chronosequence (treatments 2017, 2007, and 2001) and two control areas. We analyzed the species richness, floristic composition, life-forms, and floristic similarities of those transects, identifying 27 species of mosses (18 genera; 11 families) and 26 species of liverworts (20 genera; 16 families). Ditrichaceae was the principal moss family and Cephaloziellaceae the principal liverwort family. The life-forms encountered were turf (43 %), weft (38 %), thalloid (10 %), and mat (9 %). Turf predominated among mosses (85 %), and weft among liverworts (62 %). Species richness and floristic compositions varied among the post-fire gradients. The grouping dendrogram and ordination diagram evidenced greater similarity among transects within the same area. However, there was no evident gradient of floristic composition along the post-fire gradient, and further studies will be needed to quantify environmental gradients and their influences on bryophyte composition

The Northeastern Brazil has xerical vegetation with different biomes. Its botanical heterogeneity represents shelter for diverse fauna. The region is rich in bees, which demand the resources offered by the plants, and provide pollination services. Bee pollen has been used as a beneficial food source for humans due to its high nutritional content and being a natural antioxidant. Pollen analysis can determine the plant species visited by bees, using them as the source of pollen supply. This study aimed to identify the main pollen types present in the pollen collected by Apis mellifera in the Northeastern Brazil and to define its botanical affinity. Commercial bee pollen samples produced in the region were treated by acetolysis method, mounted on slides, and the frequency of occurrence was estimated for each type of pollen. It was possible to distinguish 113 pollen types belonging to 35 botanical families, distributed in 92 genera. Fabaceae and Asteraceae were the families that most contributed to pollen types. Pollen types of Cocos nucifera and Myrcia were found in more than 50% of the samples. The families Arecaceae and Fabaceae showed high beekeeping potential. There is a striking similarity between the pollen samples from the states of Pernambuco and Rio Grande Norte.

We describe a new species of Blechnum from Mato Grosso, Brazil: Blechnum rivulorum sp. nov. This new species was discovered as a result of visits to the herbaria BM, K, P, PR, and S, as part of the Reflora Project, by the first author. We also indicate its position in a new Blechnum phylogeny. Additionally, we confirm the occurrence of Blechnum meridense Klotzsch in Brazil and provide an updated key to all species of Blechnum in the country.
