As leguminosas são usadas para compor Sistemas Agroflorestais, cujo sucesso de implantação depende de informações básicas sobre as espécies que compõem os diferentes extratos. Hymenaea intermedia var. adenotricha é uma leguminosa com potencial para aproveitamento agroflorestal na região. As sementes foram coletadas de matrizes na área de floresta natural da Província Petrolífera de Porto Urucu - Amazonas. O estudo foi realizado em condições de viveiro e laboratório da Faculdade de Ciências Agrárias (UFAM). A semente de Hymenaea intermedia var. adenotricha é eurispérmica, com testa de consistência pétrea (desidratada) e cartácea (hidratada). O tegumento apresenta quatro estratos celulares com o primeiro formado por células finas e longas em paliçada, sendo visível a "linha lúcida". O embrião é axial, total, de cor amarelo-esverdeado. Os cotilédones são carnosos, inteiro com radícula escondida. A plúmula é rudimentar. A germinação é epígea fanerocotiledonar, com emergência curvada. A plântula apresenta sistema radicular pivotante com raiz primária axial, sub-lenhosa, estriada, glabra. As raízes secundárias são curtas, pouco ramificadas, porém entrelaçadas, resinosas e sem nódulos. O protófilo é composto, com folíolos opostos, sésseis. O primeiro metáfilo apresenta-se composto, bifoliolado, com folíolos assimétricos levemente falcado-oblongo. Species from the Leguminosae family are used in Agroforestry Systems. Their successful implementation depends on basic information about the species that constitute each extract. Hymenaea intermedia var. adenotricha is a specie from the leguminosae family with potential to be used in agroforestry in the Amazon region. The seeds were harvested from plants found in the natural forest of Petroleum Province Urucu Harbor. The studies were carried out under laboratory and nursery conditions at the Agrarian Sciences College the Amazonas University. H. intermedia var. adenotricha seeds are eurispermic, the tegument showed stone consistency when dehydrated and soft consistency when hydrated. The seed tegument showed four cellular strata, the first layer was formed by thin cells organized in a palissade. The embryon axis was yellow green. The cotyledons were fleshy with a hidden radicle. The plumule is rudimentary. The seed germination is phanero-epigeal, showing curved body during its emergency. The seedling showed tap-root root system, the axial primary root was woody grooved and glabrous. The secondary roots were resinous, short, slightly ramified but interlaced and showed no nodules. The protophyll exhibited compound asymmetric leaflets which were slightly falcade and oblonge. The first metaphyll presented compound asymmetric leaflets with slightly falcade-oblonge shape.
