“…As identificações das espécies foram feitas com base em características morfológicas, por análise comparativa de exsicatas revisadas por especialistas e fotos de coleções-typus e ainda por consulta a bibliografias específicas (Howard 1961;Brandbyge 1986;Cialdella 1989;Melo 1998Melo , 2000Melo , 2003Pendry 2004;Melo & França 2006 A terminologia morfológica está de acordo com Radford (1974); a nomenclatura para os frutos seguiu Spjut (1994) e para a confirmação dos nomes dos táxons foi consultado o sítio IPNI (2015).

ResumoPolygonaceae tem ampla distribuição no Brasil e foi registrada em diferentes domínios fitogeográficos. Os representantes desta família são reconhecidos por apresentar folhas simples, alternas e inteiras, caules e ramos com nós e entrenós bem delimitados e estípulas concrescidas que envolvem completamente o caule (ócrea). O presente trabalho teve como objetivo realizar o levantamento florístico e atualizar a distribuição geográfica das espécies de Polygonaceae ocorrentes no estado do Ceará. Para as análises morfológicas, descrições e elaboração dos mapas de distribuição foram consultadas coleções herborizadas e amostras obtidas em expedições de campo realizadas no período de março/2012 a maio/2015. As identificações foram baseadas em coleções-tipos e literatura especializada. No estado do Ceará foram registradas 13 espécies e quatro gêneros. Coccoloba (6) foi o mais representativo em número de espécies, seguido de Polygonum (5), Ruprechtia (1) e Triplaris (1). As espécies ocorrem predominantemente em ambientes mais secos como floresta estacional decidual (mata seca) e savana estépica (caatinga). Esta família constitui um importante componente da flora do Ceará, onde foram registrados 44% dos gêneros e 13,68% das espécies ocorrentes no país. Coccoloba parimensis, Polygonum acuminatum e Ruprechtia laxiflora constituem novas ocorrências para o estado. Palavras-chave: distribuição, florística, Neotrópicos, Nordeste do Brasil. AbstractPolygonaceae has wide distribution in Brazil and was recorded in different phytogeographic domains. The members of this family are known for their simple, alternate and entire leaves, stems and branches with welldelimited nodes and internodes, and fused stipules (ochrea), which sheathe the whole stem. This study aimed carry out the floristic inventory and update the geographical distribution of Polygonaceae species that occur in Ceará state. Herbarium collections and samples collected at field expeditions between March/2012 and May/2015 were used to morphological analysis, descriptions and preparation of distribution maps. The identifications were based on collections-types and specialized literature. In Ceará state, 13 species and four genera were registered. Coccoloba (6) is the most representative genus on species number, followed by Polygonum (5), Ruprechtia (1), and Triplaris (1). These species occur predominantly at drier environments, such as seasonal deciduous forest (mata seca), and stepic savannah (caatinga). This family is an important component of flora of Ceará, where were registered 44% of the genera and 13.68% of the species cited for Brazil. Coccoloba parimensis, Polygonum acuminatum e Ruprechtia laxiflora are new records for the Ceará state.

“…Estas características a diferenciam de Ruprechtia laxiflora, espécie mais próxima, que possui medula maciça e perianto frutífero expondo o pericarpo. Ocorre no Brasil e Peru (Brandbyge 1986). Em território brasileiro possui registros para as regiões Nordeste (AL, BA, CE, MA, PB, PE, PI), Centro-Oeste, Sudeste (MG) e Sul (PR) (BFG 2015).…”

The tropical rainforest of Amazonia is one of the most species-rich ecosystems on earth, with an estimated 16000 tree species. Due to this high diversity, botanical identification of trees in the Amazon is difficult, even to genus, often requiring the assistance of parataxonomists or taxonomic specialists. Advances in informatics tools offer a promising opportunity to develop user-friendly electronic keys to improve Amazonian tree identification.Here, we introduce an original multi-access electronic key for the identification of 389 tree genera occurring in French Guiana terra-firme forests, based on a set of 79 morphological characters related to vegetative, floral and fruit characters. Its purpose is to help Amazonian tree identification and to support the dissemination of botanical knowledge to non-specialists, including forest workers, students and researchers from other scientific disciplines.The electronic key is accessible with the free access software Xper², and the database is publicly available on figshare: https://figshare.com/s/75d890b7d707e0ffc9bf (doi: 10.6084/m9.figshare.2682550).

“…Triplaris is strictly dioecious, with the majority of species distributed in lowland, humid environments, although some are also present in more arid regions, including seasonal or deciduous forests. All species of Triplaris are pioneers and they play an important role in the process of ecological succession (Brandbyge ; Sanchez ).…”

Reproductive biology and pollination ecology of Triplaris gardneriana (Polygonaceae): a case of ambophily in the Brazilian Chaco

Triplaris gardneriana (Polygonaceae) is a dioecious pioneer tree reported as insect-pollinated, despite possessing traits related to anemophily. Here, we analyse the possible roles of insects and wind on the pollination of this species to establish whether the species is ambophilous. We carried out observations of floral biology, as well as on the frequency and behaviour of pollinators visiting flowers in a population of T. gardneriana in the Chaco vegetation of Brazil. We conducted experimental pollinations to determine the maternal fertility of female plants and whether they were pollen-limited, and we also conducted aerobiological experiments to provide evidence of how environmental factors influence atmospheric pollen dispersal. The population comprised an area of approximately 152.000 m and was composed of 603 female and 426 male plants (sex ratio = 0.59:0.41). We observed 48 species of insects visiting flowers of T. gardneriana, of which the bees Scaptotrigona depilis and Apis mellifera scutellata were the most effective pollinators. We recorded pollen grains dispersed by wind on 74% of the glass slides placed on females, located at different distances (1-10 m) from male plants. Airborne pollen concentration was negatively correlated with relative humidity and positively correlated with temperature. Our observations and experimental results provide the first evidence that T. gardneriana is an ambophilous species, with pollen dispersal resulting from both animal and wind pollination. This mixed pollination strategy may be adaptive in T. gardneriana providing reproductive assurance during colonisation of sites with different biotic and abiotic conditions.
