          Abstract

          RESUMO No presente trabalho foi analisada a morfologia polínica de dez espécies medicinais da família Asteraceae (Achillea millefolium L., Baccharis trimera (Less.) DC., Bidens pilosa L., Chromolaena laevigata (Lam.) R.M.King & H.Rob., Emilia sonchifolia (L.) DC., Galinsoga parviflora Cav., Matricaria chamomilla L., Senecio brasiliensis Less (Spreng.), Solidago chilensis Meyen. e Sonchus oleraceus L.) ocorrentes na referida região. Os grãos de pólen apresentaram características morfológicas comuns como presença de 3(4)-cólporos, endoaberturas lalongadas, diferindo nas dimensões das estruturas, estrutura da exina e no aspecto dos espinhos. A família Asteraceae se mostrou euripolínica na região dos Campos Gerais e os agrupamentos formados podem ser utilizados nas pesquisas que necessitem da certificação botânica pela Palinologia de produtos medicinais oriundos de flores dessa família.

          ABSTRACT We analyzed the pollen morphology of ten medicinal species of Asteraceae (Achillea millefolium L., Baccharis trimera (Less.) DC., Bidens pilosa L., Chromolaena laevigata (Lam.) R.M.King & H.Rob., Emilia sonchifolia (L.) DC., Galinsoga parviflora Cav., Matricaria chamomilla L., Senecio brasiliensis Less (Spreng.), Solidago chilensis Meyen., and Sonchus oleraceus L.) occurring in that region. The pollen grains showed common morphological characteristics such as the presence of 3(4)-colpori and lalongate endoapertures, differing in dimensions of the structures, exine structure, and aspect of the spines. The Asteraceae showed eurypalynous pattern in the region of Campos Gerais and the formed groups can be used in research requiring botanical certification by Palynology in medicinal products derived from flowers of this family.
