Abstract
La familia Asteraceae representa aproximadamente un 12% de las especies de plantas con flores en el mundo. Se estima que tienen un origen entre 50-70 millones de años y que han evolucionado rápidamente, lo que ha permitido que ocuparan diversos tipos de hábitats, incluso convirtiéndose en malezas de los humedales. Se dan a conocer las especies acuático-palustres de Paraguay, para lo cual se realizaron colectas botánicas y se revisaron especímenes depositados en diferentes herbarios. Se identificaron 32 especies que habitan los humedales, siete de ellas en ambientes lóticos, 27 en lénticos y 10 estrictamente acuáticas. La tribu mejor representada es Eupatorieae, seguida de Vernonieae. Solo una especie se reporta como endémica. Es aún escaso el conocimiento sobre la flora de los humedales, por lo que es necesario aumentar las colecciones en esos hábitats.
The Asteraceae family represents about 12% of the species of flowering plants in the world. It is estimated that they originated around 50-70 million years ago, have evolved quickly, and colonized various types of habitats, even becoming wetland weeds. The aquatic-palustrine species of Paraguay are disclosed, for which botanical collections were made and specimens deposited in different herbaria were reviewed. In total, 32 species inhabiting the wetlands were found, seven of them belong to lotic environments, 27 to lentic and 10 strictly aquatic. The best represented tribe is Eupatorieae, followed by Vernonieae. Only one species is reported as endemic. Knowledge about the flora of wetlands is still scarce, so it is necessary to increase the collections in these habitats.
