    Abstract: Abstract The interspecific limits of several taxa of Dalechampia were analyzed and clarified. Fourteen species were recognized for the genus, 10 of them endemic to Brazil. Most species are widely distributed and recorded in several sub-regions of the Pernambuco state, occurring mainly in the Zona da Mata and Agreste, in sunny environments. The most used characters for differentiation of species were the shape of leaf, stylar column, and bracteal stipules, plus number of pistillate sepals. In this work, keys for identification, descriptions, comments about morphological affinities and geographical distribution, and illustrations are provided.

    Abstract: Amanoa (Phyllanthaceae, Phyllanthoideae) has a pantropical distribution with its center of diversity in the Amazon Basin, but it has not received a recent taxonomic revision. This paper aims to treat the taxonomy of the genus, with emphasis on the Brazilian species. Collections in Brazilian and foreign herbaria were examined under stereomicroscopy with the dissection of vegetative and reproductive organs, and species were re-described and illustrated. The following species were studied: A. almerindae, A. congesta, A. cupatensis, A. glaucophylla., A. gracillima, A. guianensis, A. nanayensis, A. neglecta, A. oblongifolia, A. pubescens, and A. sinuosa. Amanoa pubescens is reestablished and illustrated for the first time. For A. glaucophylla the pistillate flower and illustration are presented for the first time, as well as the staminate flower for A. almerindae, the pistillate flower for A. oblongifolia, and the floral bud and pistillate flower for A. sinuosa. New locality records: Amanoa almerindae for Pará, Amanoa cupatensis for Acre, A. glaucophylla for Pernambuco and Bahia, A. guianensis for Pernambuco and Sergipe, A. neglecta for Brazil (Amapá), A. oblongifolia for Acre and Bahia, A. pubescens for Brazil (Amazonas), and A. sinuosa for Amapá and Pará. Monoecism in A. glaucophylla is registered.

    Flora das cangas da Serra dos Carajás, Pará, Brasil: história, área de estudos e metodologia
    FapUNIFESP (SciELO) ; 2016

    Abstract: Abstract Back in 1960 researchers from the Museu Paraense Emílio Goeldi (MPEG) began to study the Serra dos Carajás, resulting in an important series of collections, giving interesting insights in the local flora. During the last decades, intensification of expeditions to the FLONA Carajás was driven by the discovery of a high number of endemic species, coupled with mining pressure in the area. The project "Flora das cangas da Serra dos Carajás" was established in 2014 through the collaboration between MPEG and Vale Institute of Technology - Sustainable Development (ITVDS), which aimed to record systematically the knowledge of the flora associated with the cangas of the Serra dos Carajás. Nearly fifteen thousand exsiccatae currently held at several herbaria (MG, BHCB, HCJS, INPA, IAN, NY and RB) served as the base for the compilation of this flora that includes, so far, 151 families including bryophytes, ferns and seed plants. Here we present a short history of the botanical studies carried out in the region, as well as the characterization of the study area and the methodology followed by this project. This introductory chapter heads the first volume of the Flora of the cangas of the Serra de Carajás, presenting the first 55 plant families, four of bryophytes (two of mosses and two liverworts), two of lycophytes, eight of ferns, one gymnosperm and 40 families angiosperms, treating 139 genera and 248 species.

    Abstract: Informações documentais sobre a Serra dos Carajás, compiladas até o ano de 1983, foram publicadas em dois volumes pelo Museu Paraense Emílio Goeldi. Tais volumes não contemplaram informações sobre a maioria dos estudos ambientais e em biodiversidade feitos na área, com a participação de pesquisadores do Museu Goeldi. Atualmente, há uma demanda crescente por informações sobre o assunto, o que vem sendo constatado através de inúmeras consultas feitas por pesquisadores do Brasil e do exterior, notadamente sobre a fauna, a flora e o ambiente daquela região. Sendo assim, o objetivo deste levantamento é fornecer uma compilação atualizada e comentada sobre as pesquisas realizadas em Carajás por pesquisadores da instituição e colaboradores, como um apêndice complementar deste número especial.

    Abstract: For accurate interpretations of palaeopalynological data, it is important to understand the influence of the current vegetation composition and characteristics on the formation of the palynological assemblage recorded in artificial or natural pollen traps. Therefore, in this study, modern pollen rain was characterized using artificial pollen traps under different ecological conditions and climatic seasons in Trilha da Mata Lake, Carajás North Ridge, southeastern Amazonia. The collection of pollen rain data comprises the total period from September 2015 to August 2016. There were two periods of low rainfall (September to December 2015 and May to August 2016) and one period of high rainfall (January to April 2016). The first two periods were represented by a predominance of canga vegetation pollen relative to forest pollen. Under dry conditions, the associations among the taxa Aparisthmium/Alchornea, Myrcia and Bellucia dichotoma were considered important for forest ecosystems, while those among Pleroma, Hyptis parkeri, Borreria and Perama carajensis were considered important for canga ecosystems. Under wet conditions, the forests were well represented by Schefflera, Anthurium lindmanianum, Pseudopiptadenia suaveolens and Glycydendron, and the most represented canga vegetation in the pollen rain were Poaceae undif., Miconia, M. acutistipula var. ferrea and Psychotria. Aparisthmium/Alchornea and Poaceae undif. Aparisthmium/Alchornea was related to periods of low water availability, and Poaceae undif. was associated with marshy or flooded environments. Thus, an increase in the influx of Poaceae undif. pollen grains was determined by variations in the extension of flooded areas, indicating an increase in the amount of rainfall and not the opposite case. Thus, future studies on vegetation reconstruction must consider modern pollen assemblages to precisely determine paleoenvironmental and paleoclimate conditions during sediment deposition.

    Abstract: As Rubiaceae estão representadas na Área de Proteção Ambiental (APA) de Algodoal/Maiandeua por 17 espécies, distribuídas em 15 gêneros. As tribos com o maior número de espécies foram Gardenieae, com quatro, e Spermacoceae, com três. Guettarda e Psychotria apresentaram duas espécies cada um, os demais gêneros apenas uma. Três espécies de Rubiaceae da restinga foram sinonimizadas, Alibertia myrciifolia Spruce ex K. Schum. (= Cordiera myrciifolia (Spruce ex K. Schum.) C. Persson & Delprete), Psychotria barbiflora DC. (= P. hoffmannseggiana (Willd. ex Roem. & Schult.) Müll. Arg.) e Tocoyena sprucei Standl. (= T. brasiliensis Mart.). As espécies de Rubiaceae encontram-se mais concentradas na formação de mata de Myrtaceae, diminuindo, em número de espécies, em direção à praia. Guettarda spruceana Müll. Arg., Oldenlandia tenuis K. Schum., Posoqueria latifolia (Rudge) Roem. & Schult. e Retiniphyllum schomburgkii (Benth.) Müll. Arg. são novos registros para a APA de Algodoal/Maiandeua.

    Abstract: The vernacular names usually used in commercial inventories may group together distinct species. To investigate this problem, the botanical identification of trees called Tauari were examined were examined in commercial inventories of 100 ha located in the central and eastern lumber regions of the State of Pará. Field characters of each species were noted. Information about the relative distribution of this species, the technological characteristics of the timber of each species and Brazil's federal laws relating to forest management is discussed. In the central region, 112 individuals were recorded as Couratari guianensis and six individuals as Couratari sp. After revision, using botanical material collected from each tree and identified using herbarium material, the following species listed as Couratari guianensis were found: Couratari guianensis, C. oblongifolia and C. stellata (the most abundant) and specimens listed as Couratari sp. included both Cariniana micrantha and C. decandra. In the eastern region, 33 individuals were recorded by the company as Couratari guianensis, but the scientific identification showed the existence of two species: C. guianensis (the most abundant) and C. oblongifolia. C. tauari also was seen growing nearby. This study shows that correct determination of the can be obtained from field characters (leaves, branches and trunks). Botanical identification is demonstrated as fundamental for the knowledge of the regional diversity and essential for successful management plans.
