Flora Da Reserva Ducke, Amazonas, Brasil: Combretaceae

Terminalia L. has a pantropical distribution, almost exclusively constituting tropical Combretaceae. In this work, a comprehensive synopsis of all the native species of Terminalia s.s. in the Brazilian Amazon is presented, including diagnostic characters, identifi cation key, illustrations, geographic distribution maps, diversity and richness patterns with a new occurrence in Brazil, and a table with conservation status and number of records/ protected areas and their protected areas for all species. This information seeks to support the identifi cation of these tree species, in addition to actions to conserve trees in the Brazilian Amazon.

Resumo Aqui se apresenta a Flora de Combretaceae do Rio Grande do Norte, Nordeste do Brasil, com base na análise comparativa dos caracteres morfológicos de espécimes depositados nos herbários ASE, EAC, FUEL, HEPH, HST, HUEFS, IPA, JPB, MAC, MBM, MOSS, NY, UEC e UFRN, bibliografias especializadas e fotos de coleções-tipo. Para o Rio Grande do Norte são registradas 12 espécies em cinco gêneros: Buchenavia (1 sp.), Combretum (7 spp.), Conocarpus (1 sp.), Laguncularia (1 sp.) e Terminalia (2 spp.). Combretum duarteanum Cambess., C. fruticosum, T. mameluco são novos registros para o estado e Terminalia cf. amazonia poderá ser confirmada como tal, a partir de coleta de espécimes completos. Chaves de identificação para gêneros e espécies, descrições, dados de distribuição geográfica, comentários taxonômicos e ilustrações das espécies são fornecidos.

, FABÍOLA VITTI MÔRO 5 RESUMO -O trabalho foi realizado com o objetivo de descrever morfologicamente os frutos, sementes e plântulas de castanheira. Foi feita a biometria dos frutos e das sementes e sua caracterização quanto à forma, por meio de mensurações com paquímetro e observações realizadas em estereomicroscópio com câmara clara. Os frutos de castanheira são carnosos, indeiscentes, do tipo nucóide, glabros, de coloração verde a vinácea, projeção das nervuras carpelares externamente evidentes, com epicarpo delgado, mesocarpo carnoso e esponjoso de coloração vinácea, com feixes vasculares conspícuos em corte transversal. Geralmente, cada fruto contém apenas uma semente. As sementes são exalbuminosas, de formas alongadas e cilíndricas, recobertas por endocarpo rígido de coloração marrom; possuem cerca de 2,5cm, 0,7cm e 0,7cm, de comprimento, largura e espessura, respectivamente. A germinação das sementes de castanheira é epígea, e a plantula é fanerocotiledonar. Termos para indexação: germinação, reflorestamento, arborização, biometria, chapéu-de-sol. MORPHOLOGY OF THE FRUIT, THE SEED AND THE SEEDLINGS OF CHESTNUT TREE (Terminalia catappa L. -COMBRETACEAE)ABSTRACT -The work was carried out with the objective of describing morphologically the fruits, seeds and seedlings of chestnut tree. It was made the biometry of the fruits and seeds with a digital pachymeter and its characterization in relation to the shape, in stereomicroscope with clear chamber. It can be evidenced that the chestnut tree fruits are fleshly, indehiscent, nucoid, glabrous, from green to purple coloration, with evident projection of the carpel ribbings, with a fleshly and spongy epicarp and mesocarp, of purple color, with conspicuous vascular bundle in transversal cut. Generally, it has a seed per fruit. The seeds are unalbuminous, of prolongated and cylindrical shape and recovered with a rigid endocarp of brown coloration. The seeds possess about 2,5; 0,7 and 0,7 cm, of length, width and thickness, respectively. The germination of the seeds of chestnut tree is epigeal and the seedling is fanerocotyledonary.
