This research investigated four different species of aquatic macrophytes with natural occurrence in an urban environment highly anthropized Southern Brazil. The aim the was to compare phytoremediation potential among E. anagallis, H. grumosa, ranunculoides, and S. montevidensis through Pearson´s correlation analysis cluster analysis, using heavy metal content identified HNO3 - HClO4 indexes. re...

The genus Ranunculus L., with a worldwide distribution, is the largest member of the Ranunculaceae. Here, nuclear ribosomal internal transcribed spacer (ITS) sequence data and chloroplast trnLF sequence data were used to analyze phylogenetic relationships among members of the annual and perennial (Group Praemorsa, Group Rhizomatosa, Group Grumosa and Group non-Grumosa) species of Ranunculus...

Ranunculus L. with about 600 species is the largest genus in the Ranunculaceae. Problems in the taxonomy of the genus are due to high variability and polymorphism among different individuals and populations of certain species. Morphological characters of nectar scale have been considered as valuable taxonomical characters in some perennial species in some groups (Praemorsa, Grumosa, Rhizomatosa...
