| Esse estudo descreve a variação genética de 55 acessos de Passiflora spp., constituídos de P. edulis, P. alata, P. coccinea, P. caerulea, P. foetida, P. giberti, P. macrocarpa, P. macrocarpa x alata, P. serrato digitata, P. suberosa e um acesso Passiflora sp. Vinte e dois descritores morfológicos foram avaliados sobre plantas isoladas em sistema de espaldeira e permitiram estruturar a diversidade encontrada. As relações filogenéticas entre os acessos, avaliadas pela análise de componentes principais e de distâncias genéticas, mostraram existir ampla diversidade entre as espécies estudadas. Algumas espécies mostraram caracteres monomórficos. Importante variabilidade foi observada dentro de P. alata e de P. edulis, e pequenas divergências foram encontradas... |

| Abuta é um gênero taxonomicamente complexo devido à sobreposição de variação dos caracteres morfológicos. O presente estudo consiste no tratamento taxonômico de Abuta no Estado do Pará. A análise envolveu amostras provenientes de coletas e exsicatas dos herbários Museu Goeldi (MG), Instituto Agronômico do Norte (IAN), Instituto Nacional de Pesquisas da Amazonia (INPA), Jardim Botânico do Rio de Janeiro (RB) e New York Botanical Garden (NY). São apresentados chave de identificação, descrições, distribuição geográfica, comentários e ilustrações das espécies. O gênero está representado na área por 11 espécies: A. barbata, A. brevifolia, A. candollei, A. grandifolia, A. grisebachii, A. imene, A. obovata, A. rufescens, A. sandwithiana, A. solimoesensis e A.... |

| The biological spectrum and diaspores dispersal syndromes of the species recorded in a stretch of vegetation in a semi-arid region within the Cariri Environment Protection Area, Boa Vista, Paraíba State (northeast) Brazil, are described. Collections were made from fertile specimens, preferentially bearing fruit, over a 15-month period. Life forms and syndromes were determined by field observations using specialized literature. One hundred and sixty-six species, distributed into 123 genera and 41 families, were reported. Abiotic syndromes (autochory and anemochory) represented 69.7% of all syndromes identified, whilst 30.3% of the species were classified as zoochory. In the life form spectrum therophytes represented 27.7% of species, followed by small- and... |

| Senna includes about 300 species with circumtropical distribution, widely represented in the Americas, also occurring in Africa, Australia, Asia and Oceania. The genus is represented in Brazil by 80 species, of which 26 are endemic. The Serra Geral de Licínio de Almeida (SGLA), situated in the central portion of the Cadeia do Espinhaço, state of Bahia, Brazil, presents areas relatively little studied, with great potential for the registration of new information about Brazilian biodiversity. The floristic survey of Senna in the SGLA included analysis of specimens collected from February 2012 to October 2013. The analyses were supplemented with dried collections from the following herbaria: ALCB, BHCB, HUEFS, HUNEB, HRB, MBM and SPF.The genus is represented... |

| This work aimed to study the effect of the Calophyllum brasiliense seed coat on the seed germination process. To this end, three experiments were conducted in laboratory, greenhouse and screenhouse. From a total of six treatments, five are related to the seed coat (mechanical scarification; mechanical scarification followed by 2 hours in water, chemical scarification, hot water immersion and complete seed coat removal) and one control. Laboratory and greenhouse experiments were conducted in a completely randomized design (CRD). Screenhouse experiment was conducted in a completely randomized block design (RBD). We evaluated the total percentage, the speed index and the average time of germination or emergence. Data were subjected to analysis of variance and... |

| Studies related to floral biology are essential for the understanding of the ecological relations between different species, and the beginning of breeding programs. In this way, the aim of the study was to elucidate aspects of floral and reproductive biology and floral visitors of this species. Information about floral morphology and morphometry, anthesis, nectaries and pollinator attractive structures, characterization of floral visitors, receptivity of androcytic stigma and maturation, in vitro pollen storage and germination, and characterization of the reproductive system were obtained. The guabiju tree has hermaphrodite flowers, and the floral opening occurs mainly during the night, but also in the morning. Anthers are the main attractive structure to... |

| Senna comprises about 300 species with circuntropical distribution, widely represented in the Americas, also occurring in Africa, Australia, Asia and Oceania. The Brazil includes 80 species, of which 27 are endemic, 50 reported from Bahia and 22 recorded from the Caatinga. The floristic survey of Senna in the Ecological Station Raso da Catarina included analysis of specimens collected March 2010 to October 2011. The analyses were supplemented with dried collections from the following herbaria: ALCB, EAC, HRB, HUEFS and MBM. Seven taxa were recorded. The most representative taxa in the area were Senna rizzinii H.S.Irwin & Barneby and S. acuruensis (Benth.) H.S.Irwin & Barneby var. acuruensis. The genus can be found in a variety of environments... |
