    Abstract Among the Brazilian Stachytarpheta, the small group of species treated as the Stachytarpheta longispicata complex is morphologically recognised by its inflorescences with pedicellate flowers. This character is also present in S. longibracteata and S. rizzoi, two new species herein described based on the morphological species concept. Both species have a restricted distribution in the Cerrado domain, with S. longibracetata found in the Jalapão region (State of Tocantins) and S. rizzoi in the Serra Dourada region (State of Goiás). Detailed diagnosis, morphological comparisons, line drawings, ecological and taxonomic data, provisional conservation status, and a distribution map are provided for each new species. With these findings, we improve the taxonomy of the S. longispicata complex by increasing the number of known species to seven, and providing an identification key for this peculiar group with pedicellate flowers exclusive to the Cerrado.

    Abstract Mapping diversity patterns is important to clarify its causes and is essential information for conservation policies. We map the distribution of vascular epiphytes from the Southern block of the Brazilian Atlantic Forest (SBAF) to understand the main factors responsible for the richness and species turnover, as well as to generate information for the conservation of this functional group. We gathered a data set of vascular epiphytes, mapping the richness and weighted endemism using cells of 0.5° × 0.5°, and performed two Generalized Dissimilarity Models (GDM) using a filter of 18 and 54 species in cells of 5 km × 5 km to evaluate the species turnover and correlation with the climatic and topographic factors. We found four sites presenting both a high richness and endemism. A gradient of richness and species turnover between the coastal and inland regions was confirmed, as well as between the lowlands and the mountainous regions. The main predictors obtained from GDM were geographic distance, cloud cover, and temperature seasonality. The topographic heterogeneity and the resulting climate changes are responsible to enhance the richness and species turnover of vascular epiphytes in the SBAF. It is important to conserve the coastal areas and the mountainous gradients due to the high richness and strong species turnover, but also the inland areas since their composition is quite distinct from previous environments.

    Abstract The present work aimed to study the distribution and richness of Gesneriaceae in the Serra da Mantiqueira (SM), located in Southeastern Region of Brazil, as well as to evaluate the conservation degree of endemic species and possible areas of endemism of this Serra. The analyzed data were obtained from the literature, as well as from eight herbariums with representative collections of the SM, from field expeditions and an online database, and then marked on a map which was divided into 0.5° × 0.5° grid squares. Richness grid similarity analyzes were performed for the 55 species found, while a parsimony analysis of endemism and the conservation status evaluation were only performed with the 15 endemic species of Gesneriaceae registered for the SM. The highest richness was found for Northern Mantiqueira and the similarity between the squares confirmed the two SM sectors and the existence of a relationship between the interior of the ES and the Zona da Mata of MG. The 15 endemic species of the SM should be considered threatened to some degree due to restricted distribution, reduced populations and/or anthropogenic impact in their occurrence habitats. Given this richness, there is an imminent need for conservation policies which truly guarantee effective protection of the SM, as it represents a relevant refuge for species in general.

    Abstract Urbanization is a disturbance process that can select species and result in biodiversity homogenization. Despite this, urban green areas shelter nature and are also important to human welfare. Epiphytes are an important functional group present in such areas, that are rarely studied. We evaluated the vascular epiphytic component in 26 urban green areas in the Brazilian Atlantic Forest and tested hypotheses related to the anthropogenic disturbances: 1) the community of epiphytes in urban green areas presents low richness and diversity of species; 2) there is low beta diversity due to flora homogenization represented by a reduced set of more tolerant species to disturbance. A total of 2288 trees (1563 representing phorophytes) and 110 epiphytic species were sampled. Six species were dominant, resulting in low diversity values, but some green areas had relatively high richness. The similarity found between the majority of the sampled areas suggests that epiphytic flora is subject to homogenization due to environmental filters. We found a high richness of species without adaptations to the epiphytic lifeform (accidental epiphytes) (42% of total sampled). Some results suggest that more comprehensive ecological and/or floristic studies about the epiphytes in the urban environment are necessary, such as Orchidaceae as the second richest family (since it is often poor in urban areas). More information about the species distribution patterns are necessary, both regarding the anthropized environments and the relationships with exotic or native phorophytes, as well as to enhance the knowledge of the ecological functions played by the epiphytes in these places.

    Abstract The Neotropical Region (NR) is one of the areas with the most plant diversity globally, and its richness of vascular epiphyte (VE) species is higher than Africa and Asia combined. This richness is a consequence of the heterogeneous climate and geological history of the region, both factors also being responsible for the plant distribution patterns. Here, we aimed to explore the phytogeographic relationships of the VE in the NR using 14,636 identified records from 173 surveys exclusively of VE, carried out in 14 countries and 23 biogeographic provinces, comprising 3849 identified species. We assessed the floristic patterns and relationships with climatic variables by multivariate analysis (cluster and ordination analyses). The clustering formed 13 main groups, partly corresponding to the biogeographic units of the NR. Our results demonstrate consistent floristic patterns confirmed through the analysis of floristic similarity, corroborating previous biogeographic classifications in well-studied areas, while broader patterns were found in poorly studied areas. We found a floristic gradient pattern, which allowed us to understand the relationships between environmental conditions and floristic patterns. Furthermore, we discuss our results under the light of the history that likely shaped the current distribution patterns and richness of the VE in the NR. The VE proved to be an important model for testing biogeographic classifications. We encourage the studies of this synusia in the several geographical gaps that remain in the NR, which undoubtedly will improve further studies and support conservationist policies.

    Abstract Epiphytes are constantly exposed to light, water and nutrient stress, and thereby they frequently show anatomical adaptations in response to their habit. We aimed to investigate the variation in foliar anatomical traits of epiphytes along vertical stratification. We hypothesized that different species from varied groups would show a variation in foliar anatomical traits that would reflect the variation in microclimatic variables found across phorophyte strata. To address our hypothesis, we studied 23 vascular epiphyte species from different groups (ferns, magnoliids, monocots, and eudicots), occurring on ten phorophytes from a trail at an Atlantic Rainforest fragment in southeastern Brazil. We measured six microclimatic parameters at different phorophyte heights: light intensity, temperature, relative air humidity, altitude, evaporation rate, and wind speed. We then collected expanded-leaf samples for quantitative and descriptive anatomical evaluation, seeking to detect possible correlations between structural traits and microclimatic variations. We found that overall the analyzed species showed pronounced xeromorphic characters in response to epiphytic habit, such as thick outer periclinal wall of pavement cells, lignified epidermis, multiseriate epidermis, stomata below the level of pavement cells, water-storing tissues, and parenchymatous cells with wall thickenings, among others. In most epiphytes, we also found a trend for thicker mesophyll in plants exposed to higher light intensity along different phorophyte strata. The ecophysiological significance of these adaptations is discussed in detail. Our hypothesis was accepted, since we found that species from different groups showed a variation in foliar characters that reflected the variation found in microclimatic parameters along phorophyte strata. Some anatomical traits, e.g. thick mesophyll, were influenced by height differences along phorophytes and by the consequent variation in light intensity along vertical stratification, while other traits were directly related either to the epiphytic habit, especially to the water and nutrient deficits imposed by it, or to the taxonomic group, as seen in ferns.

    Abstract Passiflora L. is the most representative genus of Passifloraceae. In Brazil, its species are widely distributed through phytogeographic domains and altitudinal gradients, including the Atlantic montane forests of the Southeast region. In these forest remnants, expressive species richness has been found. The aim of this work was to evaluate the distribution patterns and status conservation of Passiflora species in Serra da Mantiqueira (SM), a mountain range located in southeastern Brazil that stands out for its high biological diversity. We obtained data on species distribution through collections in the field, herbaria collections and compiled online databases, which were plotted on shapefile overlay maps. Species richness, collection effort and similarity among grid squares were analyzed for the taxa recorded. To evaluate distribution patterns by altitudinal gradient, we employed a similarity analysis by altitude class and a test of significance. Considering the states that encompass the SM, Minas Gerais showed the highest Passiflora richness. On the other hand, grid square 13, located in the mountainous region of Espírito Santo state, concentrated the greatest species richness. Similarity analysis between grid squares pointed to the Septentrional area of SM having the most diverse floristic composition. We observed the highest richness and occurrence record between 500 and 1500 m. A gradual change in species composition occurred along the altitudinal gradients, with decline in richness from 1000 m. Around 85% of the species were recorded outside protected areas, reinforcing the need for actions for their conservation through the expansion or creation of conservation units.

    Abstract Arthrocereus belongs to the Cactaceae family, which comprises 124 genera and 1438 species distributed throughout the Americas. The present study aimed to investigate pollen morphology, to provide taxonomic and phylogenetic value for the knowledge of the group, in order to clarify the relationships among its taxa. Ten taxa were analyzed: A. glaziovii, A. melanurus subsp. magnus, A. melanurus subsp. melanurus, A. melanurus subsp. odorus, A. rondonianus, A. spinosissimus, one possible new species (sp.1), and three taxa with difficult taxonomic delimitation close to A. melanurus (sp.2, sp.3, sp.4), being six accepted taxa and four of uncertain position. The pollen grains was acetolyzed, measured and described, electron photomicrographs were taken, and multivariate analysis was conducted. Descriptions, measurements and photomicrographs are presented. Arthrocereus can be characterized by presenting pollen grains which are large, isopolar, oblate spheroidal, prolate spheroidal and subprolate, with a very small to small polar area, subcircular and subtriangular amb, 3–6-colpate with long to very long colpi; microechinate exine, perforations with conspicuous to inconspicuous annuli. Palynological results indicate two morphological patterns in the studied taxa: the first (I) is related to the 3-colpate pollen grains and the second (II) to the 3–6-colpate pollen grains. The principal component analysis and hierarchical cluster analysis confirm the separation of species using quantitative pollen grain variables. The analysis of the pollen grains revealed that the genus is stenopalynous and there is significant overall correspondence in the pollen variations among the taxa, which provides support of taxonomic and phylogenetic value for future studies in the genus.

    Abstract This study aims to analyse the available distributional data about epiphytic Angiosperms of the Brazilian Atlantic forest (BAF) in order to define geographic distribution patterns, areas of higher species richness and endemism, and locate knowledge gaps regarding the epiphytic flora. Thus, we seek to enhance the knowledge of the biogeography of these species and highlight priority areas for their conservation. Distribution data from literature and collections housed in 51 herbaria were compiled and submitted to analyses of richness (species count per distribution grid), similarity and parsimony analysis of endemicity. The regions of higher richness and endemism, chiefly in Rio de Janeiro and Espírito Santo, overlap with those found for trees and animal groups, while the location of some areas of endemism coincide with the supposed existence of Pleistocene forest refuges in Brazil’s Northeastern and Southeastern regions. The Doce River seems to be responsible for the division of the Angiosperm epiphytic flora into north and south sectors of the BAF. In addition, the existence of a discontinuity named here as ‘Falha de Conde’ (Conde’s Gap) situated in the northern corner of the State of Bahia was highlighted. Such gap divides the north sector of the BAF into two segments. It was also found that the hydrographic basins influence the delimitation of those areas. Subsampling of parts of the range leads to information gaps that need to be addressed by further data collection to ensure an improved understanding of the biogeographic relation between some of the regions, and also to fully clarify their delimitation.

    Abstract The Brazilian Atlantic Forest presents high levels of richness and endemism of several taxonomic groups. Within this forest, the Orchidaceae may be highlighted as the richest family of Angiosperms found there, and is highly threatened due to collection and habitat destruction. The inselbergs of the Brazilian Atlantic Forest are mostly unknown regarding their floristic composition, but the available information points to occurrence of endemic species, with adaptations to survive to this dry environment. The objectives of this study were to conduct a floristic survey of the Orchidaceae species on the Maciço do Itaoca, an inselberg located in the Northern region of the State of Rio de Janeiro, make a comparative analysis with other sites in Eastern Brazil, and discuss the geographic distribution, floristic relationships and conservation status of the orchid species present on the inselbergs. The floristic composition of the study area was compared with 24 other locations in Eastern Brazil (of which 13 are inselbergs) and the influence of the types of surrounding vegetation on the composition of the Orchidaceae flora on the inselbergs. On Maciço do Itaoca we recorded 18 species from 17 genera: Brasiliorchis picta, Brassavola tuberculata, Campylocentrum robustum; C sellowii, Catasetum luridum, Cattleya guttata, Cyclopogon congestus, Cyrtopodium glutiniferum, Leptotes bicolor, Lophiaris pumila, Miltonia moreliana, Oeceoclades maculata, Phymatochilum brasiliense, Prescottia plantaginifolia, Pseudolaelia vellozicola, Sarcoglottis fasciculata, Sophronitis cernua. and Vanilla chamissonis. The highest floristic similarity was with the Pedra da Botelha (0.43), an inselberg located in the North of Espírito Santo. This result is probably due to the similarity in altitude and distance from the coast in both areas despite the geographical distance between them. Apparently, little influence is exerted by the types of surrounding vegetation on the composition of the flora of inselbergs, due to their unique environmental characteristics which exert a strong selection pressure on plants that are adapted to survive on these inselbergs. The threats observed to the species on this inselberg are the same as for other inselbergs and include the collection of ornamental species, fire and quarrying. Specifically for the Maciço do Itaoca, a possibility for conservation may be the annexation of this area to the Desengano State Park, an important conservation area in the Northern of the State of Rio de Janeiro.
