| Objetivando auxiliar trabalhos taxonômicos e farmacobotânicos, foram realizados estudos morfoanatômicos dos órgãos vegetativos de Piper crassinervium H.B. & K. (jaborandi). O material foi analisado seguindo-se técnicas usuais de corte e coloração. P. crassinervium é um arbusto de caule ereto, de folhas estipuladas e alternas. Dentre as características anatômicas importantes para a sua identificação destacam-se: parênquima cortical radical com esclereídes; córtex caulinar com faixas descontínuas de colênquima e tecido vascular organizado em dois círculos descontínuos de feixes colaterais, delimitados por endoderme com estrias de Caspary; folha dorsiventral, hipoestomática, com estômatos ciclocíticos e tetracíticos e hipoderme unisseriada, porém, com... |

| The morphology and structure of the flowers and fruits of Chamissoa altissima (Jacq.) Kunth during the development were analyzed. The plant material was fixed in FAA 50, embedded in historesin and sectioned according to standard techniques. The flowers presented tepals with betalain and homogeneous mesophyll; receptacular nectary; anthers with epidermis, endothecium, one middle layer, and uninucleate tapetum; and monocarpelar ovary with homogeneous mesophyll. The fruit was a circumscissile capsule, presented the same number of cellular layers that the ovary, and possessed subendocarpic sclerenchyma. The seed was bitegmic, exotestal and perispermic. |

| Euphorbiaceae s.l. presents several morphological types of fruits, of which the schizocarp is the most common. The fruits of weed species of Euphorbia graminea Jacq., Euphorbia heterophylla L., Euphorbia hirta L. (= Chamaesyce hirta (L.) Millsp.) and Euphorbia prostrata Aiton (= Chamaesyce prostrata (Aiton) Small) are objects of this study. Inflorescences and fruits in development were collected on the campus of the State University of Maringa (UEM), Brazil, fixed in FAA 50 and glutaraldehyde, dehydrated and sectioned with a rotary microtome according to standard morphology and anatomy techniques. The species present several anatomical similarities, though there are some differences related to the outer epidermis of the ovaries, which is glabrous in E.... |

| Piperaceae species of forest remnants of Maringá, Paraná, Brazil present vegetative propagation through root or stem (stolon). This reproduction type was verified in Piper amalago L., P. arboreum Aublet, P. xylosteoides (Kunth) Steud., Peperomia parnassifolia Miq. and Ottonia martiana Miq. Root and stem branches of these species were analyzed anatomically. Results indicated that the vegetative propagation in Piperaceae should be studied in other forests. New and additional studies should be made if the structural variations were induced environmentally or fixed genetically. |
