Abstract The Lecythidaceae clade has a pantropical distribution and comprises 24 genera and 355 species. Ten genera and 121 species occur in Brazil, where species richness is highest in Amazonia. Four genera and 14 species were recorded in Espírito Santo, as well as two cultivated species. Important characters used to identify the species are the morphology of the bark, shape and size of the leaves, presence and shape of trichomes on the leaves and inflorescences, inflorescence type, morphology and color of the perianth (especially the petals), morphology of the androecium, shape and dimension of the fruits and seeds, and morphology of the arils. Identification keys, descriptions, illustrations, and comments for the taxa are provided.

Abstract This study aimed to carry out a floristic inventory and update the geographical distribution of Portulacaceae species that occur in the state of Ceará, Northeast Region of Brazil. The field expeditions for collection and observation of species were realized between March/2015 and March/2021. Six species of Portulaca have been recorded in the state of Ceará, being identified mainly by habit, margin and leaf shape, flower coloration, operculum shape, and seed ornamentation. All species occur in Conservation Units in the state of Ceará: P. elatior, P. halimoides, P. mucronata, P. oleracea, P. pilosa and P. umbraticola. The highest floristic richness was found in the Stepic Savanna, where all species were recorded. Portulaca halimoides had the widest distribution in Ceará, with 17 records, occurring in various vegetation types, especially in the Stepic Savanna. Portulaca mucronata was registered exclusively in Stepic Savanna, being the species with the lowest number of records. Identification key, descriptions, comments about the species, taxonomic relationships, phenological data and photographs of the species are presented here.
摘要本研究旨在对巴西东北部塞埃尔州马齿苋科植物进行区系清查和地理分布更新。在2015年3月至2021年3月期间进行了物种采集和观察的实地考察。马齿苋有6种，主要通过习性、边缘和叶片形状、花的颜色、盖的形状和种子的纹饰来识别。所有的物种都出现在cerear州的保护单位:P. elatia, P. halimoides, P. mucronata, P. oleracea, P. pilosa和P. umbraticola。植物区系丰富度最高的是草原稀树草原，记录了所有物种。马齿苋(Portulaca halalimoides)在中亚分布最广，共有17个记录，分布于各种植被类型，尤以草原稀树草原为最。马齿苋(Portulaca mucronata)仅在草原稀树草原登记，是记录数量最少的物种。本文介绍了该物种的鉴定关键、描述、评论、分类关系、物候资料和照片。

Abstract Belonging to Malpighiales, Humiriaceae has about 65 species in eight genera, distributed almost exclusively in the Neotropics, occurring from southern Brazil to Central America. In Brazil, 35 species have been recorded (ca. 54% of the family’s diversity), wherein the greatest diversity is found in the Amazon (27 spp.), Atlantic Forest (9 spp.) and Cerrado (6 spp.) domains. This work is part of the “Flora do Espírito Santo” project, which aims to contribute to the knowledge of the state’s floristic diversity. Field expeditions were carried out from January/2019 to March/2020. Humiriaceae, in the state of Espírito Santo, is represented by six species distributed in four genera: Humiria, Humiriastrum, Sacoglottis and Vantanea. Among the registered genera, Vantanea is the most diversified, with three species. In the dense rain forest, all Humiriaceae species recorded here were found, followed by pioneer formations of restingas, with four species and seasonal semideciduous forest, with one species. The main morphological characters that assist in the delimitation of Humiriaceae species in Espírito Santo, are androecium characteristics, such as length (homodynamous or heterodynamous), number of stamens and the number of their series, as well as anther morphology.
葎草科(Humiriaceae)，隶属于麻豆属，共有8属65种，几乎全部分布于巴西南部至中美洲的新热带地区。在巴西，已记录到35种(约占该科多样性的54%)，其中在亚马逊(27种)、大西洋森林(9种)和塞拉多(6种)领域发现的多样性最大。这项工作是“Flora do Espírito Santo”项目的一部分，该项目旨在促进对该州植物多样性的了解。实地考察于2019年1月至2020年3月进行。位于Espírito Santo州的Humiriaceae有6个种，分布在Humiria、Humiriastrum、Sacoglottis和vantea四属。在已登记的属中，万塔尼亚属的种类最多，共有3种。在茂密的雨林中，发现了所有记录的葎草科物种，其次是休息林的先驱形成，有4种，季节性半落叶林，有1种。在Espírito Santo，雄蕊科的主要形态特征是雄蕊的长度(同质或异质)、雄蕊数和雄蕊系列数以及花药形态。

Abstract Understand the role of the drivers in vegetation pattern is essential in ecology since diversity plays a major role in the stability and maintenance of plant communities. The murundus are small and scattered earthmounds with a differentiated flora of its surrounding. In our study site (Campo Maior, Piauí, Northeastern Brazil), we classified them in three categories: presence of carnaúba (PC), presence of tucum (PT), and with the absence of palm trees (AP). Here, our goals were (1) to explore alpha diversity using the richness estimator and abundance distribution rank, expecting that palm trees could influence the richness of plant species on murundus; (2) analyzing the species richness-area relationship in the murundus, following the assumptions that the largest one holds more species; (3) find the changes in the species composition (beta diversity) between the three categories of murundus, assuming which the presence of palm trees influence the species composition; and (4) investigate if the distance between murundus is a decisive factor in the species composition, where the closest murundus are the most similar in species composition. Ours results showed that palms trees do not influence the richness of the murundus, the largest murundus are the richest ones, and the turnover predominantly determines beta diversity in the different murundus categories. Furthermore, the distance between the murundus did not determine its floristic similarity. Overall, we demonstrated which the species of palm trees are not the main drive of the plant assemblage in the murundus, however its size comprises a major factor in the richness, with great species substitution, which explains the high plant diversity.

Abstract We examined the diversity and distribution of Caryocaraceae, Hypericaceae, and Rhizophoraceae in Ceará State, Brazil. Floristic treatments were carried out based on comparative analyses of the morphological characters of specimens from several Brazilian herbaria (ALCB, EAC, HCDAL, HST, HUEFS, HVASF, IAN, MBM, MOSS, SP, UEC and UFMT), the scientific literature, and photographs of type collections. Each family is represented here by a single species. Caryocar coriaceum occurs predominantly in the southern portion of Ceará State in typical open (cerrado) and forested savannas (cerradão). Vismia guianensis is widely distributed and occurs in several vegetation types, but mainly ombrophilous forests and savannas. Rhizophora mangle has a narrow distribution range, being recorded in coastal vegetation with fluvial and/or lacustrine influences (mangrove swamps). All three species were recorded in designated Conservation Areas. An identification key for the species, morphological descriptions, commentaries on their conservation, habitats and phenologies, as well as photographs and illustrations are provided.

Abstract A new species of Cryptanthus, known exclusively from Chapada Diamantina, in the municipalities of Miguel Calmon and Jacobina, state of Bahia, Northeast Brazil, is described and illustrated. Cryptanthus euglossinii is characterized by having leaves that are reddish in the marginal region, white-scaly near the base and glabrous adaxially towards the apex, with the abaxial surface covered by trichomes that obscure the color of the leaf. Comparisons are made with two similar species, C. reisii and C. bibarrensis, that are considered closely related. Euglossinii bees were observed visiting the flowers of C. euglossinii and collecting floral essences on petals, a relationship that is the basis of the epithet of the new species. Cryptanthus euglossinii is considered Endangered (EN) based on an extent of occurrence of 860 km2, an area of occupancy of 1,000 km2, and criteria established by the IUCN.

Abstract Historia Naturalis Brasiliae, a reference work for Brazilian natural sciences, contains information on species observed by 17th century naturalists. Among the reports, the botanical family Fabaceae deserves to be highlighted among the taxa that make up the Brazilian flora due to its richness of species and economic interest. In this sense, the objective of the present study was to retrieve information regarding Fabaceae cited in Historia Naturalis Brasiliae by naturalists Piso & Marggraf (1648), with the aim of identifying potential resources of Brazilian flora in conjunction with local knowledge about potential species today and how historical changes have influenced the use of these plant resources. Documentary data were analyzed in the original source and in Pickel’s 2008 review work (Flora do Nordeste do Brasil). The information was organized in a database and analyzed qualitatively and quantitatively. The analysis recovered 49 species belonging to the botanical family Fabaceae in the work. Of this total, 33 species and two genera had their use mentioned in the work, the reports of which were subdivided into four categories, with the highest percentage being for the category of medicinal use (69.23%). Of the plants reported for medicinal use, 18 species and one genus had no records in contemporary works. The analyses presented here contribute to expanding the knowledge of Fabaceae, the recovery of knowledge of plants from past centuries, and the discussion of the influence of factors that cause historical changes in use patterns, thus enriching studies in the field of botany, particularly historical ethnobotany.
摘要巴西自然科学参考书《巴西自然历史》收录了17世纪博物学家观察到的物种信息。在这些报告中，植物科Fabaceae因其丰富的物种和经济价值而值得在构成巴西植物群的分类群中突出。从这个意义上说，本研究的目的是检索博物学家Piso和Marggraf(1648)在《巴西自然史》中引用的关于Fabaceae的信息，目的是结合当地对当今潜在物种的了解，确定巴西植物群的潜在资源，以及历史变化如何影响这些植物资源的利用。在原始来源和Pickel 2008年的评论工作(Flora do Nordeste do Brasil)中分析了文献数据。这些信息被组织在一个数据库中，并进行定性和定量分析。结果表明，本研究共回收植物科豆科植物49种。其中33种2属有文献提及其用途，又分为4类，其中药用类所占比例最高(69.23%)。其中药用植物18种，1属在当代文献中未见记载。本文的分析有助于扩大对豆科植物的认识，恢复过去几个世纪以来对植物的认识，并讨论导致利用模式历史变化的因素的影响，从而丰富植物学领域的研究，特别是历史民族植物学的研究。

Abstract Moringa oleifera is an arboreal plant belonging to the family Moringaceae distributed in tropical areas and has gained enormous attention in the last decades. This research is a review on the association between aqueous extracts of M. oleifera leaves and diabetes mellitus and understanding its pharmacological functions and underlying mechanisms. The research refinement demonstrated the pharmaceutical potential of M. oleifera and its phytochemicals, given its antidiabetic effect. The prospective analysis showed the amount of application within IPC A61K in health area. The secondary metabolites present in M. oleifera, glucosinolates, flavonoids, and phenolic compounds may be responsible, in part, for the disease control hypoglycemic actions. Glucosinolates, when metabolized by salivary enzymes, give rise to sulforaphanes that act in preventing type 2 diabetes and in reducing insulin resistance. Flavonoids interact with intestinal enzymes by modifying carbohydrate metabolism by regulating glycemic levels, in addition to increasing insulin sensitivity. Phenolic compounds increase the expression of glucose transporters (GLUT4) and reduce the synthesis of fatty acids and cholesterol, contributing to the reduction of glucose resistance and blood sugar control. Moringa oleifera can be used as complementary therapy of the type-2 diabetes.

Abstract Pterodon pubescens and P. emarginatus (Leguminosae) are native medicinal plants of Brazil. Extractivism due to its therapeutic properties threatens populations of both species. Studies of genetic diversity is a way to reason the use and promote conservation. We developed microsatellite markers for P. pubescens and transferred them to P. emarginatus to further genetic diversity investigation of these species. From genomic sequences of P. pubescens, obtained via the Illumina MiSeq platform, it was possible to identify 6,514 microsatellite regions, to design 5,419 primer pairs, and to test 30 markers amplification. We provide 26 polymorphic microsatellite markers, 10 of which were genotyped in 48 individuals per species. The number of alleles per locus range from 3 to 16, with high average genetic diversity ( P. pubescens HE = 0.753; P. emarginatus HE = 0.691). The genotyped markers have a high paternity exclusion probability (Q values greater than 0.99) and low probability of identity, indicating that set of loci is capable of individual discriminating in P. pubescens and P. emarginatus. Microsatellite markers provided in this study are a tool for population genetics studies and conservation of the two species and can be applied to closely related non-model species.
摘要:短毛翼龙(terodon pubescens)和豆科植物marginatus是巴西的本土药用植物。由于其治疗特性，提取会威胁到这两个物种的种群。对遗传多样性的研究是合理利用和促进保护的一种途径。本研究开发了短毛假杨的微卫星标记，并将微卫星标记转移到狭尾假杨中，以进一步研究该物种的遗传多样性。利用Illumina MiSeq平台获得的pubescens基因组序列，鉴定了6514个微卫星区，设计了5419对引物，并检测了30个标记扩增。我们提供了26个多态性微卫星标记，其中10个标记在每个物种的48个个体中进行了基因分型。每个位点的等位基因数在3 ~ 16个之间，平均遗传多样性较高(P. pubescens HE = 0.753;P. emarginatus HE = 0.691)。该基因型标记具有较高的父系排除概率(Q值大于0.99)和较低的同一性概率，表明该基因座组在短毛假松和叶尖假松中具有个体区分能力。本研究提供的微卫星标记是种群遗传学研究和保护这两个物种的工具，可以应用于近亲非模式物种。

Abstract Some actions made by the botanist João Barbosa Rodrigues, during his term as director of the Jardim Botânico do Rio de Janeiro (1890-1909), indicate an exaltation of the Brazilian Monarchy. In the history of the institution published in Hortus fluminensis (1894), Rodrigues described a scene in which the regent prince John VI, when solemnly founding the garden in 1809, would have planted an imperial palm with his own hands, a specimen known as palma mater. The period was full of political tension, due to the sudden change of government with the Proclamation of the Republic, on November, 15, 1889. In this article we discuss whether the name of Rodrigues was a consensus for director of the garden. Although he was recognized in Brazil and abroad as an important Brazilian scientist, he was a steadfast Monarchist. In this context, we present a critical analysis of the discourse involving the palma mater. The results suggest this discourse is historically unlikely, leading us to believe it is the case of an ‘invented tradition’ by the new director, expressed as an allegory with political goal. Other studies are necessary to better understand his goals, his interlocutors and possible reactions provoked by such manifestation.
