“…The species of this family are often cited as pioneers and frequently occupy rocky outcrops, ruderal environments, disturbed areas, and forest and road edges (Lucena and Alves, 2010;Alves, 1999;Silva et al, 2010;Araújo et al, 2010).…”

a b s t r a c t Edited by J FloresKeywords: Ethnobiology Plant diversity Local botanical knowledge Euphorbiaceae stands out among angiosperms in its species richness and in the number of reported uses from ethnobotanical surveys in Brazil and other tropical countries. In Brazilian semiarid regions, species of Euphorbiaceae are among the most frequently used by rural communities, especially for medicinal purposes. The present study investigated the presence of species of Euphorbiaceae and their use by a rural population from the Araripe National Forest region, a protected area located in the Chapada do Araripe (NE Brazil). This area is considered to be of primary importance for conservation, and it is lacking in scientific research. The survey of the richness of Euphorbiaceae occurred through opportunistic plant collections and phytosociological studies between August 2011 and June 2012. We performed 153 interviews with informants who were selected based on general nonprobabilistic household sampling and administered semi-structured interviews using a checklist interview that considered all the species of the family Euphorbiaceae registered in collections. We found 23 species of Euphorbiaceae, with the genus Croton (5 species) being highlighted. This study adds new occurrences of Euphorbiaceae to the region compared with the results found in previous surveys; 50% of the collected Euphorbiaceae species were considered useful, with Manihot esculenta (cassava) considered of the highest importance, with a higher utilization rate in the community ponds. The study also indicated the use of castor bean (Ricinus communis), Croton heliotropiifolius, and Jatropha gossypiifolia. The category of use that was most cited was medicinal, and most of the useful species were obtained by informants in anthropogenic areas. The richness of Euphorbiaceae in the region was representative; however, further studies should be conducted in the study area. The dynamics of Euphorbiaceae use in the studied rural population did not appear to pose a threat to native species within the conservation area.

“…Apesar desta expressiva representatividade no Brasil, a principal referência para identificá-las é ainda a obra de Müller (1873). Estudos menos abrangentes são as floras regionais elaboradas por: Smith et al (1988); Cordeiro (1992Cordeiro ( , 1995 e Alves (1998). Merecem destaque ainda a revisão elaborada por Cordeiro (1993) e o estudo taxonômico desenvolvido por Lucena (2001).…”

RESUMO Foi realizado estudo da ultraestrutura dos tricomas foliares em microscopia eletrônica de varredura (MEV) de 14 espécies do gênero Croton, ocorrentes nas zonas do litoral e da mata do estado de Pernambuco, com o objetivo de caracterizar morfologicamente cada tipo de tricoma, como recurso auxiliar na delimitação das espécies e ainda relacionálos à classificação de Webster. Foram registrados 10 tipos de tricomas: estrelado-porrecto, fasciculado, multiradiado, dendrítico, lepidoto, estrelado-rotado, estrelado-lepidoto, dentado-lepidoto, simples e glandular. Na maioria dos taxa predomina o tipo estrelado-porrecto; apenas uma espécie apresenta tricoma do tipo lepidoto. Foi possível observar que cada espécie mantém constante seu (s) tipo(s) de tricoma revelando, portanto, ser o tipo de tricoma um caráter relevante na taxonomia do gênero.

“…The Euphorbiaceae family, which is considered one of the largest families of Angiosperms, covers about 7,800 species distributed in approximately 300 genera and 5 subfamilies worldwide [9]. These species occur preferentially in tropical and subtropical environments [10,11]. Among the main genera belonging to this family, there is Jatropha L., which belongs to the subfamily Crotonoideae, Jatropheae tribe and is represented by about 200 species.…”

This review paper focuses some basic aspect of the taxonomic, biology, cultivation, chemical composition, bio-diesel potential, medicinal values and uses of Jatropha curcas Linn. The genus Jatropha is distributed throughout the tropics and sub-tropics growning in marginal lands and is a potential biodiesel crop worldwide. Due to its adaptability to marginal soils and environments the cultivation of Jatropha curcas is frequently mentioned as the best option for producing biodiesel. The seed oil can be used as a feed stock for biodiesel. Alternatively Jatropha oil is used in soap, glue or dye industry. The seed cake is rich in nitrogen and phosphorus and can be used as manure. Ash from the roots and branches of Jatropha curcas L. is used as cooking salt, and as lye in dyeing. The dark blue dye extracted from the bark of Jatropha is a useful dye. The plant parts and its oil along with its latex used for different reasons such as pesticides, anti-inflammatory activities, wound healing, lighting (lamp), bio-gas production, fertilizer and other purposes. The objective of this review paper focuses some basic aspect of the taxonomic, biology, cultivation, chemical composition, bio-diesel potential, medicinal values and uses of Jatropha curcas Linn.
