In this work we present taxonomic notes for the genus Erechtites. More specifically, we present evidence for the re-establishment of E. petiolatus, a species that was hitherto being considered as a synonym of either E. valerianifolius or E. valerianifolius f. prenanthoides. Thus, we raise to six the number of accepted species of Erechtites. We present field photographs of E. petiolatus and E. valerianifolius and assess the conservation status of these species. Furthermore, we present taxonomic notes for E. valerianifolius and Senecio prenanthoides.
