Martius (Arecaceae) is popularly known as "jacitara". It presents several ethnobotanical indications with the use of its fibers in baskets and ropes. The objective of this work was to characterize the anatomy of the vegetative organs of the species in a dryland environment. Collected at the Research Campus of the Museu Paraense Emílio Goeldi, the material was submitted to the usual techniques in plant anatomy and histochemistry and photomicrographed. For the SEM analysis, the images were obtained at the Institutional Laboratory of Scanning Electron Microscopy of MPEG, through an electron microscope LEO model 1450 VP.

The spines can present elongated and short, straight and recurved forms that occur in the same individual and in different regions. Regarding the anatomical aspects, it is noticed that in O. polyacanthos the pinnules present epidermal cells of the abaxial surface similar to the adaxial one; the epidermal appendages are denser in the abaxial one.

The epidermis is covered by a slightly thickened cuticle, followed by a thin-walled, irregular hypodermis. The mesophyll consists of poorly differentiated chlorenchyma with irregular and juxtaposed cells, interrupted by fibrous bundles lined up towards the margin. The vascular bundles, in all regions, are collateral, some with bipartite phloem, partially or totally involved by fibrous clusters and a parenchymatous sheath. In the stem there is an extensive fibrous sheath surrounding the vascular bundles. In the root there is amyliferous parenchyma, aerenchyma of lysigenous origin and lateral roots originating from the pericycle. It is noticed that the species has specific characteristics and great presence of fibers in the stem, thus justifying its use for various types of handicrafts. O. polyacanthos C. Martius (Arecaceae) é conhecida popularmente como "jacitara". Apresenta várias indicações etnobotânicas com o uso de suas fibras em cestarias e cordoalhas. O objetivo deste trabalho foi caracterizar a anatomia dos órgãos vegetativos da espécie em ambiente de terra firme. Coletado no Campus de Pesquisa do Museu Paraense Emílio Goeldi, o material foi submetido às técnicas usuais em anatomia e histoquímica vegetal e fotomicrografados. Para a análise em MEV, as imagens foram obtidas no Laboratório Institucional de Microscopia Eletrônica de Varredura do MPEG, através de um microscópio eletrônico LEO modelo 1450 VP. Quanto à morfologia, observa-se que existe uma variedade na distribuição e forma dos espinhos. Os espinhos podem apresentar formas alongadas e curtas, retos e recurvados que ocorrem no mesmo indivíduo e em regiões diferentes. Quanto aos aspectos anatômicos, percebe-se que em O. polyacanthos as pinas apresentam células epidérmicas da superfície abaxial semelhantes à adaxial; os apêndices epidérmicos encontram-se mais adensados na abaxial. Possuem complexo estomático do tipo tetracítico e as folhas são anfihipoestomáticas e os tricomas são pluricelulares bífidos. Esta epiderme é revestida por uma cutícula levemente espessada, logo abaixo se segue uma hipoderme de paredes delgadas e irregulares. O mesofilo é constituído por clorênquima pouco diferenciado com células irregulares e justapostas, sendo interrompidas por feixes fibrosos enfileirados em direção a margem. Os feixes vasculares, em todas as regiões, são colaterais, alguns com floema bipartido, envolvidos parcial ou totalmente por agrupamentos fibrosos e uma bainha parenquimática. No caule há extensa bainha fibrosa envolvendo os feixes vasculares. Na raiz há parênquima amilífero, aerênquima de origem lisígena e raízes laterais oriundas do periciclo. Percebe-se que espécie possui características específicas e grande presença de fibras no caule, justificando assim sua utilização para os diversos tipos de artesanatos. 2023-07-11T17:55:43Z 2023-07-11 2023-07-11T17:55:43Z 2008-07-03 Resumo SANTOS, Ana Carla Feio dos; POTIGUARA, Raimunda Conceição de Vilhena; SANTOS, Seidel Ferreira dos.
