| Aspects of the morpho-anatomy of developing fruits and seeds of Clusia parviflora are presented and discussed as a continuation of the study of these organs in Clusiaceae. The fruit is a septifrage capsule; the suberized exocarp is derived from the external epidermis of the ovary. The mesocarp originates from the ovarian mesophyll and remains parenchymal in nature. The endocarp is derived from the internal epidermis of the ovary and the endocarp is derived from the inner ovary epidermis as well as from three to four adjacent subepidermal layers, with tangentially elongated cells which become lignified and contribute to fruit dehiscence. The ovules are anatropous, bitegmic, with an endothelium, and give rise to equally anatropous seeds. The exotesta has... |

| 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... |

| It is known that the efficient dispersal is one among other features that amplify the invasion potential of a plant. Knowledge of the ontogeny, morphology and fruit dispersal of species is indispensable for weed control in crops. To identify the pericarp structures involved in the fragmentation and dehiscence processes and other features related to dispersal, we studied the pericarp development of Aeschynomene evenia Wright, Desmodium incanum (Sw.) DC. and Vigna luteola (Jacq.) Benth. (Fabaceae-Faboideae), all of which are considered weeds in certain situations. For light and scanning electron microscopy studies, we fixed and processed buds, flowers and fruits, according to usual methods, at different stages of development. We observed that the... |

| 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. |
