Resumo: Eichhornia azurea and E. crassipes are morphologically easy to distinguish, however, their seeds are similar and differentiated only by size, which makes their identification difficult, especially when collected directly from the seedbank. We identified characters for distinguish seeds of these species through macrosculpture analyzes of the seed coat (size, shape, epidermal pattern, the structure of the primary and secondary microsculpture, funiculum, hilum, micropyle, raphe), using scanning electron microscopy. The species differ mainly by the secondary sculpture pattern, with perforated in E. azurea and wrinkled with micropapillae in E. crassipes; the external tissue of seed with smooth aspect in E. azurea and irregularly wrinkled in E. crassipes; and raphide crystals in E. crassipes. Our results contribute to taxonomy of the tribe Eichhornieae and future studies on the microsculpture analyzes of the macrophytes seed coat, in a comparative approach to understand ecological and evolutionary aspects.

Identificamos caracteres para diferenciar as sementes dessas espécies através de análises de microescultura do revestimento das sementes (tamanho, forma, padrão epidérmico, estrutura da microescultura primária e secundária, funículo, hilo, micrópila, rafe), utilizando microscopia eletrônica de varredura. As espécies diferem principalmente pelo padrão secundário de escultura, sendo perfuradas em E. azurea e enrugadas com micropapilas em E. crassipes; tecido externo da semente com aspecto liso em E. azurea e enrugado irregularmente em E. crassipes; cristais de ráfide em E. crassipes. Nossos resultados contribuem para a taxonomia de Eichhornieae e para estudos futuros de análises de microesculturas do revestimento de sementes de macrófitas, em uma abordagem comparativa para entender aspectos ecológicos e evolutivos.Iheringia.
