Vascular epiphytes stand out in tropical forests in terms of diversity. However, no comprehensive review of the group in the Amazon region has been performed so far. We carried out a literature review on the scientific knowledge of vascular epiphytes in the Amazon aiming to identify the main gaps, limitations and perspectives for studies on the subject. Searches were conducted in Google Scholar, Scopus and Web of Science using inclusion and exclusion criteria. 291 articles published in the period 1933-2022, mostly the 21st century, were included in the review. Brazil was the most studied country. However, knowledge gaps were found in regions located in the Brazilian arc of deforestation as well as in areas of Bolivia, Guyana, French Guiana and Suriname. There was a predominance of studies related to the floristics, systematics and biogeography of spermatophytes and ferns, focusing on the diversity and taxonomy of certain families (e.g. Orchidaceae). However, we found gaps for more comprehensive research, considering population dynamics, dominance (biomass), guidelines for evaluation of epiphyte and systematization of data for Amazon. We indicate the need of studies focused on ecology, floral and reproductive biology, biochemistry, phytochemistry, anatomy and physiology. Future research should also consider the impacts of current trends in deforestation and climatic changes on the diversity of vascular epiphytes in the Amazon.

As part of an ongoing treatment of species of the Brevantherum clade of Solanum , a new species from the Atlantic Forest of Brazil was discovered and is described here. Solanum helix Giacomin & Stehmann sp. nov. is a species well represented in herbaria that has been overlooked for almost two centuries. It has a unique expanded non-inflated fruiting calyx that resembles a propeller and that is not found in any unarmed species of Solanum . This discovery highlights the importance of continued herbarium and field work in hyperdiverse ecosystems, such as the Atlantic Forest in South America. Taxonomic affinities are discussed and images, as well as mapped distribution, are given. A key to closely related species for NE Brazil is also provided.

Dalechampia seccoi is a new endemic species of Euphorbiaceae from the Atlantic Forest domain, southeastern Brazil. Here we describe and illustrate the new species. Collections of botanical material, and standard herbarium practices were applied. The new species is vegetatively similar to D. alata, D. erythrostyla, D. pentaphylla, D. violacea, and D. purpurata , however it is distinguished by exclusive characters such as involucral bracts 4‒5-lobed, pinkish, staminate sepals vinaceous, resin darkish and stigma yellow lobed to crateriform. The new species is restricted to Seasonal Semideciduous Forest with altitudes of ca. 700 m from Caparaó, south of the state of Espírito Santo. In addition, we provide field photographs, preliminary conservation status assessments using IUCN Red List guidelines, as well as a checklist and key for morphological correlated

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.

ABSTRACT The assessment of plant extinction is strongly influenced by the number of populations and the number of localities found for the species target. A larger population and a large number of localities, the results of the assessment will be easier to conclude. However, if the population and location of the plant are not known, even if there is only one location recorded in the herbarium, then there is a challenge in determining the final result of the assessment. This paper will reveal the challenges and the final results of the assessment where only one location is known based on the herbarium records. The species is Beilschmiedia lancifolia Miq. The species was first published in 1852 collected from Mount Ungaran, Indonesia. There have been no additional records of B. lancifolia since its first collection. To update the conservation status of the species, we conducted population assessment in Mount Ungaran using a focused survey method. In spite of the intensive surveys on each side of Mount Ungaran within the species’ known elevation range, we could not find a single individual of B. lancifolia. Based on our findings, we proposed to add the Possibly Extinct (PE) to the present status of B. lancifolia.

Intra-annual distribution of precipitation in central Amazonia often leads to a short mild dry season and an increase in irradiance, temperature, and vapor pressure deficit; however, the accurate effect of intra-annual microclimatic variability on stem growth is still under investigation. The objective of this study was to determine how stem growth responds to monthly variations in microclimatic factors in the central Amazon. During five years (2008-2012) we measured diameter stem growth of 109 trees (26 species) and used principal component regression to evaluate the effect of microclimatic variability on stem growth in diameter. We found that the mean stem growth in diameter across species increased in response to an increase in rainfall and reference evapotranspiration, but it decreased with a rise in mean and minimum vapor pressure deficit. A contribution of this study is to show that even when irradiance and temperature had no significant effect on stem growth, small changes in vapor pressure deficit significantly affect stem growth. If the dry season becomes longer, as predicted by models, trees currently more sensitive to microclimatic variability associated with droughts would be the most affected by climate changes.

Global climate change is currently a serious threat to biodiversity. The understanding of the effects of climate changes on the flora is urgent. Here, we analyze the effects of future climate change on the spatial distribution of the three remaining groups of Carapichea ipecacuanha (Poaia) in the Americas. We built niche-based models for current and optimistic and pessimistic climate scenarios projected for 2050 and 2090. Our findings showed that climatically suitable areas for the Atlantic and Amazon Forest groups will be strongly reduced. The greatest risk of extinction was observed for the Amazon group due to the drastic spatial reduction and abrupt spatial displacement of climate suitability. The climate suitability for the Atlantic Forest group will be reduced, comprising a small suitable area in the transition zone between Minas Gerais and Espirito Santo. The climate suitability for the Panama group remained in an continuous region in Panama and Colombia. Our results encourage future studies that develop conservation management plans in order to ensure the continuation of ecological refugia for this species.

Myrtaceae has ca. 6,000 species, distributed into 140 genera with Pantropical distribution. The family is one of the five most representative flowering plants in species richness in Brazilian restinga and is also of great importance for the maintenance of the ecological cycles of this vegetation. However, few studies focus on Myrtaceae in restinga, mainly in the State of Bahia, which has the country’s largest coastal extension. This study aims to present the first taxonomic study of Myrtaceae from the restinga of the State of Bahia, Brazil. A total of 10 field trips were performed from September 2016 to April 2019, and the most relevant herbaria of Brazil were consulted. A total of eight genera and 85 species of Myrtaceae were identified in the Bahian restinga. Myrcia was the most representative genus with 42 species, followed by Eugenia (23 spp.), Psidium (seven spp.), Campomanesia (five spp.), Myrciaria (four spp.), Neomitranthes (two spp.), and Blepharocalyx and Calycolpus (a single species each). Two of them represented new species to science, and four presented the first records to the studied area. The distribution patterns among the Brazilian biomes and the restinga phytophysiognomies are discussed, also a checklist, identification keys, and photographic plates are provided.
