    Begoniaceae is represented by the genus Begonia in Brazil with approximately 215 species found mainly in the Atlantic Forest in all forest physiognomies exeter in mangrove. The Espírito Santo state remaining approximately 11% of original vegetation consisted of fragments of different sizes where the most part of the richness and diversity of capixaba biota is finding. The aims of this study were listing the records of the Begonia species in the state of Espírito Santo, characterize the vegetation where they occur, the geographical distribution patterns, richness, diversity, endemism, compare their distribution with the Conservation Units of Integral Protection and areas listed as priorities for Biodiversity Conservation in Espírito Santo, set the status of conservation of species and infer similarity of the Begonia species of the Espírito santo state with the other states of Brazil. The methodology used is the most commonly used in floristic survey and taxonomy of phanerogams, literature, analysis of herbarium specimens and natural populations. In Espírito Santo state were found 53 species of Begonia, including four new species, three taxa were synonymized and one rehabilitated. Of these 53 species, 42 occur in ombrofilous forest, four in semi deciduous forest and four simultaneously in the two vegetation types. Three species occure in the Neotropics, three are endemic to South America, two occure in Brazil extra-Amazonian, 45 are endemic to the Atlantic Forest and 18 are endemic to the Espirito Santo state, included two considered microendémicas. Using the IUCN criteria, 11 species are considered Critically Endangered, nine Endangered, five Vulnerabel and two Extinct in the Wild. The highest concentration of species was observed in the mountain region. The highest richness and diversity were observed in the municipality of Santa Teresa, Santa Leopoldina, Cariacica, Vargem Alta and Castelo. The similarity analysis showed that the species of Begonia in the Espírito Santo have more similarity with Minas Gerais and later Rio de Janeiro, Sao Paulo and Bahia states. Are still provided, identification key, descriptions, distribution, habitat, etymology, comments, maps and illustrations.

    Levantamento das espécies de restinga utilizadas pelas comunidades de Pontal do Ipiranga e Degredo, Linhares, ES

    Ethnobotany is defined as the study of knowledge and concepts developed by any society about the plant world, covering either the way how the social group classifies plants, or their uses. Brazil, that is quite different, has about 40,982 species of flora and no less than 218 Indians, adding a population of approximately 350 thousand people. One of the aspects of ethnobotany is the survey of the species used by traditional communities. Such survey can serve as basis for the development of sustainable models once that natural environments such as the Brazilian Atlantic Forest, and their coastal environments, has been endangered for many years, and its original vegetation drastically diminished. Therefore, this study aimed to conduct the survey of the species known and used by communities from Pontal do Ipiranga and Degredo in order to generate data that contribute to the conservation of forest remnants and knowledge associated with them The study was done in Pontal do Ipiranga and Degredo, both localized in Linhares, ES. in area of sandbank that has been endangered by the human action. For the survey, were conducted excursions between March/2010 up to August/2010 with interviews, guided tours and collection of botanical material. The data obtained in the field were synthesized and were made qualitative and quantitative analysis, such as the value of use of species and the index of diversity. Three informers (two women in Pontal do Ipiranga and a man in Degredo) were identified by the method of Snowball. Besides, 57 people chosen randomly in both localizations, were interviewed. As the results were collected in a total of 85 species belonging 67 genus and 39 families for the both localizations. The families with the largest number of collected species were Fabaceae and Myrtaceae and the categories of use more representative were medicinal, alimentary, technology and ornamental. The ritualistic category only was registered in Pontal and honey varieties only in Degredo. The habit more often of the species in Pontal do Ipiranga was grass and in Degredo was bush and the most commonly used parts were fruits, flowers and stalk. The species with large value of use were AnacardiumoccidentaleL. and Eugenia unifloraL. with1,17 and 0,98 respectively. The diversity index of ethnobotany knowledge of the communities from Pontal do Ipiranga and Degredo was 1,67 in the base 10, considered low in relation to other studies. The main conclusions of the study are that the local informers, instead of in reduced number, can be recognized as specialist in the communities; the communities know little about of the native species more restricted; there are species, which not only useful to communities, are at risk of extinction and is critical to create a Conservation Unit in Pontal do Ipiranga and Degredo.
