During field expeditions on white sand patches in northwestern Maranhão, Brazil, we found specimens of Calea characterized by minute florets and pappuses, common to divaricata clade species. After thorough analysis, concluded that those represent a new species, which is described here as breviflora. Its description, distribution map, illustrations, taxonomic comments, information the habitat preliminary conservation assessment are provided. Moreover, present an identification key for

Species identification using DNA barcodes has revolutionized biodiversity sciences and society at large. However, conventional barcoding methods do not reflect genomic complexity, may lack sufficient variation, rely on limited loci that are universal across the Tree of Life. Here, we develop a novel method uses exceptionally low-coverage genome skim data to create “varKode”, two-dimensional image representing landscape species. Using these varKodes, then train neural networks for precise...

A synopsis of the Leguminosae from Park Nacional das Nascentes do Rio Parnaíba (PNNRP), located in northern and northeastern regions Brazil, is presented herein. total 68 species 2 infraspecific taxa belonging to 29 genera four subfamilies (i.e., Caesalpinioideae, Papilionoideae, Detarioideae, Cercidoideae) were recorded. Of these, 14 considered new records for or states encompassing PNNRP. Genera with highest number Chamaecrista (15 spp.), Bauhinia (8 Mimosa (6 spp.). Regarding plant...

Croton ludovicensis E.L.Pereira and Rossine sp. nov. is described illustrated. The new species was found in Maranhão, northeast of Brazil, growing a restinga vegetation. morphologically close to C. guianensis , from which it can be differentiated by aspects the inflorescences, shape pistillate sepals, junction styles trichomes capsules. Even though occurs protected areas, provisionally assessed as ‘Endangered' due its small populations, fragmented limited distribution. Additionally,...

ABSTRACT Interactions among organisms are important in ecosystem functioning and relevant for the management conservation of species. Here we report first record a potential ant-hemiptera-plant mutualism on Lorostemon coelhoi (Clusiaceae) Manaus, Amazonas state, Brazil. Our observations five trees indicated that presence hemiptera nymphs diverted ants from damaging flower buds while looking nectar, because secrete honeydew, which is collected by instead. Trees without produced less fruit due...

Abstract We present two taxonomic novelties in Garcinia (Clusiaceae): a new species to the Brazilian Atlantic Forest, bahiensis Mouzinho & L.Marinho sp. nov. ined., endemic hygrophilous forests of southern Bahia state, whose specimens were previously determined as G. macrophylla Mart.; and redescription guacopary (S.Moore) M.Nee, distributed transition areas between Amazon Cerrado domains that neglected previous studies. The treatment consists morphological descriptions, photographic...

Lacistema morrocoensis, a Critically Endangered species known from two localities in rocky outcrops of the Guiana Shield departments Amazonas and Vaupés, Colombia, is described illustrated. Description based on specimens collected during field expeditions carried out to document flora upper middle Apaporis River basin, including Cerro Morroco, one poorest floristic areas Colombian Amazon. As contribution flora, we also report new record L. macbridei for country provide an identification key...

Clusieae is an exclusively Neotropical tribe in the family Clusiaceae sensu stricto. Although tribes within are morphologically and phylogenetically well-delimited, resolution among genera these remains elusive. The includes estimated ∼500 species distributed five genera: Chrysochlamys, Clusia, Dystovomita, Tovomita, Tovomitopsis. In this study, we used nearly complete plastid genomes from 30 exemplar representing all recognized, plus two outgroups to infer phylogeny of using Maximum...

The consensus is that Amazonian white-sand ecosystems (campinaranas) shelter several endemic plant species. However, recent studies have shown most species are generalists, and they also occur in other Neotropical ecosystems. To investigate this issue, we analyzed the proportion of endemic/specialist a checklist trees, palms, shrubs sampled between 2014 2020 campinarana patches Uatumã Sustainable Development Reserve (USDR), central Amazon. We provide description...

Here we discuss the importance of vernacular names and encourage authors new plant species to propose “suggested names” along with description in cases that there are no known. It is not our intention rules, but provide recommendations ensure inclusion local peoples dissemination scientific knowledge when suggesting a name. We believe suggestion original publication would help [1] minimizing proliferation common same language on becomes widely publicized; [2] communicating lay audience...

Abstract Tovomita comprises approximately 50 species that are mainly distributed in moist forests of the Neotropics. In Brazil there 34 species, which occur Amazon region and along Atlantic coast. We here describe illustrate from Brazilian Forest, as well characterize leaf morphology these taxa. Leaves were cleared their venation was analyzed to look for diagnostic characters related architecture relationship between secondary intersecondary veins. Eleven recorded, have distributions ranging...

The binomial Rheedia spruceana Engl. has been considered a synonym of Garcinia gardneriana (Planch. & Triana) Zappi. When analyzing the type collections both names, we detected need to restored R. with new combination in Garcinia. This is herein proposed. We also clarify inadvertent lectotype selection for spruceana, previous interpretations specimens, and describe species fluviatilis Mouzinho L. Marinho.

Os manguezais na Ilha de São Luís/MA margeiam a costa e cursos d’água doce, mas já se encontram bastante reduzidos diante da crescente urbanização sem planejamento. Um exemplo desordenada ausência planejamento ocorre no bairro do Francisco, Luís Maranhão. Estabelece-se assim, necessidade conhecer um pouco mais sobre os manguezais, especialmente aqueles que interferem diretamente dia dos moradores. Para tanto, relatamos aqui experiência desenvolver o projeto extensão “O impacto resíduos...

The present study deals with a floristic survey of the Orchidaceae occurring in Poço Escuro reserve, municipality Vitória da Conquista, Bahia, Brazil, which was conducted through literature review, monthly field trips to area studied and analysis materials main herbaria Bahia. This work presents an identification key, descriptions, illustrations, comments on morphology, habit, phenology geographical distribution 12 species Reserve, thus contributing knowledge family state

Morphological and molecular investigations of the galphimioid clade in angiosperm family Malpighiaceae revealed that three species previously assigned to Lophanthera are more closely allied with Spachea. These transferred newly described genus Andersoniella include A. hammelii, marcelae, spruceana, type genus.

Os diários de viagem do Príncipe Maximilian Alexander Philipp Wied-Neuwied, trazem um belo relato sobre a flora, fauna e os aspectos étnicos Brasil, no início século XIX. Wied foi o primeiro fazer uma descrição Arraial da Conquista, localidade que deu origem à cidade Vitória Conquista. É dele também mais antiga se conhece vegetação região. Este trabalho teve como objetivo reunir as informações passagem príncipe por Conquista listar espécies plantas coletadas e/ou citadas ele. Foram...

RESUMO A Ilha de São Luís, Estado do Maranhão, configura-se como uma região ecotonal, um misto floresta úmida, mata-de-cocais, vegetação dunas, restingas e manguezais.
