(pupunha palm tree) has great economic potential, being cultivated mainly for the production of its fruits and heart-of-palm. The present work aimed to describe the anatomical structures of the leaves and roots in order to support other areas of scientific knowledge. The leaves were collected on the campus of Embrapa Amazônia Oriental, fixed in F.A.A.70% and later submitted to the usual techniques of plant anatomy. The illustrations were made in optical photomicroscopy, clear-camera drawings and Scanning Electron Microscopy (SEM). In frontal view the leaflet lamina of B. gasipaes presents: heterodimencional epidermal cells (adaxial and abaxial faces), with straight and slightly thickened anticlinal walls, coated by a smooth and waxy cuticle; amphistomatous lamina with tetracyclic stomata; non-glandular trichomes of two types: Filiform and Claviform. The transverse section of the leaf lamina shows: uniform epidermal cells, followed by hypodermis; dorsiventral mesophyll, uni or biseriate palisade parenchyma and multiseriate lacunate parenchyma, with idioblasts, raphids; central vein with collateral vascular bundles, involved by a sclerenchyma sheath. The petiole and rachis, in cross section, present: uniseriate epidermis coated by wax; filling tissue with tiny intercellular spaces, and in the petiole there are bands of elongated parenchymatic cells; collared vascular elements attached to a ring of sclerenchymatic fibers near the epidermis and dispersed in the central region. The root, in cross section, shows: thin cell epidermis, followed by tenuous hypodermis; sheath of exodermal fibers surrounding the cortex and medulla with alternating vascular elements. The species under study presented an anatomical structural configuration common to the genus described by Tomlinson (1961), but possessing characteristics peculiar to the species. Bactris gasipaes H.B.K(pupunheira) apresenta grande potencial econômico, sendo cultivada principalmente para produção de seus frutos e palmito. O presente trabalho objetivou descrever as estruturas anatômicas da folha e raiz visando subsidiar outras áreas do conhecimento científico. As folhas foram coletadas no campus da Embrapa Amazônia Oriental; fixadas em F.A.A.70% e posteriormente submetidas as técnicas usuais em anatomia vegetal. As ilustrações foram realizadas em fotomicroscopia óptica, desenhos em câmara clara e Microscopia Eletrônica de Varredura (MEV). Em vista frontal a lâmina do folíolo de B. gasipaes, apresenta: células epidérmicas (face adaxial e abaxial) heterodimencionais, com paredes anticlinais retas e pouco espessadas, revestidas por cutícula lisa e cerosa; lâmina anfiestomática com estômatos tetracítico; tricomas não glandulares de dois tipos: Filiformes e Claviformes. O corte transversal do limbo foliar apresenta: células epidérmicas uniformes, seguidas de hipoderme; mesofilo dorsiventral, parênquima paliçádico uni ou bisseriado e lacunoso multisseriado, com idioblastos, rafídeos; nervura central com feixes vasculares colaterais, envolvidos por bainha esclerenquimática. O pecíolo e o raquis, em corte transversal, apresentam: epiderme unisseriada revestida por cera; tecido de preenchimento com minúsculos espaços intercelulares, sendo que no pecíolo ocorre faixas de células parenquimáticas alongadas; elementos vasculares colarerais agregados a um anel de fibras esclerenquimáticas próximo a epiderme e dispersos na região central. A raiz, em corte transversal, apresenta: epiderme de células delgadas, seguida de hipoderme tênue; bainha de fibras exodérmicas circundado o córtex e a medula com elementos vasculares alternados. A espécie em estudo apresentou uma configuração estrutural anatômica comum ao gênero descrito por Tomlinson (1961), mas possuindo características peculiares à espécie. 2023-04-11T17:26:53Z 2023-04-11 2023-04-11T17:26:53Z 2002-07-04 Resumo FREITAS, Márcio da Silva Cruz; POTIGUARA, Raimunda C.
