These are considered the first scientists to explore the river and publish work on it. We highlight the intertextuality of their reports and also the process of knowledge translation between travelers and their interlocutors, an approach that we consider necessary and unavoidable for the development of this field of investigation. Our main sources are published narratives, sometimes associated with manuscripts and iconography.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67284624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are 12 genera and 30 species of the family in Brazil, a half of it occurring in the Atlantic Forest. Here we study the species of Capparaceae occurring in Espírito Santo, with the objective of expanding the knowledge about the richness of this family in Atlantic Forest. The study was based on the analysis on herbaria collections, as well as samples collected during field collections. Capparaceae in Espírito Santo state is represented by the genera Capparidastrum (1 sp.), Crateva (1 sp.), Cynophalla (2 spp.), Mesocapparis (1 sp.), Monilicarpa (1 sp.) and Neocalyptrocalyx (2 spp.). Cynophalla grandiflora is first described here. Capparaceae is commonly found at a maximum altitude of 600 m in Espírito Santo, predominantly in “tabuleiros costeiros” and coastal plains, without records in mountainous regions. Morphological characteristics of such as habitat, pubescence, tertiary veins, nectaries on leaf axils and type of fruit, are fundamental for the delimitation of the species.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Serra da Mantiqueira (SM) represents one of the main highland areas of Brazil harboring vegetation remnants, and highlighting the cloud forests. We present a checklist of the vascular epiphytes found in the cloud forests of the SM, discussing the data about taxonomic representativity, distribution in the phytogeographic domains, habits, threatened status in Brazil and the states comprising the SM (Espírito Santo-ES, Minas Gerais-MG, Rio de Janeiro-RJ, São Paulo-SP). Field expeditions were performed between 2012 and 2019, as well as data gathering from scientific collections and published articles. We found 678 species, representing approximately 20% and 30% of the species found in Brazil and Atlantic forest, respectively. The richest families (Orchidaceae, 288 spp.; Bromeliaceae, 112 spp.; Polypodiaceae 65 spp.) corroborated the patterns found in different scales. Forty-one species are threatened nationally (and regionally, there are 149 in ES, 55 in MG, six in RJ, 31 in SP). These numbers of richness and threatened species highlight the relevance of directing efforts toward knowledge and conservation of both cloud forest remnants and SM as a whole, under pain of losing of a large part of the floristic diversity of Atlantic forest.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two water regimes were evaluated, as follows: control - plants irrigated daily (I) and water deficit (S), with and without the application of 400 mg L–1 of salicylic acid (SA), totaling four treatments. Seedlings were evaluated at three times: at the beginning of the experiment (T0), that is, when the irrigation was interrupted; when the photosynthetic rate reached values close to zero (P0 - 15 days after irrigation interruption), that is, when irrigation restarted; and when the photosynthetic rate was recovered (REC). Eugenia myrcianthes seedlings were negatively affected when subjected to water restriction; salicylic acid attenuated the damage to the photosynthetic apparatus by acting positively on the relative water content in the leaves, SPAD index, photosynthetic metabolism, superoxide dismutase and peroxidase enzyme activity, and seedling growth in P0. Eugenia myrchiantes presented potential for recovery after resumption irrigation. The application of SA contributed to the maintenance of gas exchanges, photochemical processes and quality of E. myrcianthes seedlings during and after water deficit, suggesting the promotion of plant resistance induction.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to describe for the first time the anatomy of the floral nectaries in the tribe Gardenieae (Rubiaceae). Flowers from Cordiera concolor, Genipa americana, Randia calycina, Randia ferox, Randia heteromera, Randia micracantha, and Tocoyena formosawere collected, photographed, and processed using conventional techniques for observation with optical and scanning electron microscopies. In all species the nectary is differentiated histologically into epidermis, nectary and sub-nectary parenchyma, and vascular bundles. Nectar is exuded via nectarostomata. The nectaries have reproductive function, and are structural and mesenchymal during the floral stage. Whereas after corolla has fallen they are persistent nectaries, with post-floral secretion and extranuptial function. In addition, floral visitors that appeared on open flowers and after corolla fall were recorded.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67283925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alves-Araújo","doi":"10.1590/2175-7860202273000","DOIUrl":"https://doi.org/10.1590/2175-7860202273000","url":null,"abstract":"Espírito Santo ranks as the 7th Brazilian state in terms of diversity of angiosperms, ferns, and lycophytes (Dutra et al. 2015; Prado et al. 2015). This comes as a result of its variety of environments whose geographic formations extend from sea level to elevations of up to 2,892 m. Historically, the state’s development was impeded by royal decree as a way to prevent the smuggling of gold, which delayed its economic growth by at least 300 years compared to other captaincies (Nascimento 2016). This delay was also reflected in the state’s scientific development. Research institutes and universities in existence today date back to only the second half of the 20th century. This background explains the late start of scientific investigations into the flora of Espírito Santo since other Brazilian states had started cataloging theirs in the last century (e.g., Santa Catarina, which conducted the first studies of Flora Ilustrada Catarinense begun in 1951, by Raulino Reitz; São Paulo, with the project Flora Fanerogâmica do Estado de São Paulo started in 1994; and Bahia, where the Flora da Bahia project began in 1999). The real possibility of starting these investigations came only in 2008, after carrying out a diagnosis of collections deposited in different Brazilian herbaria, collected by Brazilian and foreign naturalists and taxonomists traveling through Espírito Santo. The Flora do Espírito Santo project, which aims to list, describe, produce iconographic images, and identify the distribution of species that occur in the state, is the result of meticulous and carefully considered work, discussed by researchers engaged in disseminating scientific information about Espírito Santo’s biodiversity. More than 80 researchers from 23 national and international institutions are currently engaged in this endeavor to monograph the Espírito Santo flora and fungi, thus contributing to the body of knowledge of Brazilian biodiversity and the training of professionals in plant taxonomy. An important product for the knowledge of the Flora of Espírito Santo was the 2015 publication of the manuscript “Angiosperm Checklist of Espírito Santo: using electronic tools to improve the knowledge of an Atlantic Forest biodiversity hotspot”, based on information available in virtual herbaria and on the Flora do Brasil website. This manuscript listed 6,364 species, 1,390 genera, and 180 families of angiosperms in the Espírito Santo (Dutra et al. 2015). Based on that list, the Rodriguésia Journal published a special volume in 2017, dedicated to studies of the flora of Espírito Santo, constituting a reference for that state’s flora in terms of its floristic-taxonomic treatment of 21 families, 60 genera, and 290 species of lichen, ferns, and angiosperms, 21 of which are endemic to the state (Carrijo & Mansano 2017). In this second special volume, we present the treatment for 24 families, 85 genera, and 313 species, of which 31 are endemic to Espírito Santo, and 27 represent new occurr","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67282656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
