Abstract

Descricoes anatomicas de Piper arboreum Aubl. var. arboreum e P. tuberculatum Jacq. var. tuberculatum que ocorrem na Floresta Ombrofi la Densa da Tijuca sao apresentadas neste estudo. O material foi examinado de acordo com as tecnicas usuais da anatomia. Importantes diferencas foram detectadas entre os taxons. Piper arboreum possui bainha sulcada e contem espacos intercelulares conspicuos, lâmina foliar com hipoderme biestratifi cada, parenquima palicadico uniestratifi cado e nervura principal concavo-convexa. Piper tuberculatum possui bainha de disposicao circinada, com espacos intercelulares pequenos, lâmina foliar com hipoderme uniestratificada, parenquima palicadico biestratificado e nervura principal biconvexa. As analises anatomicas corroboram em considerar os referidos taxons como distintos.
