Senecio Senecio Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, "Senecio", means "old man." Variously circumscribed taxonomically, the genus "Senecio" is one of the largest genera of flowering plants. The traditional circumscription of "Senecio" is artificial, being polyphyletic, even in its new circumscription which is based on genetic data. Despite the separation of many species into other genera, the genus still contains species and is one of the largest genera of flowering plants. As no morphological synapomorphies are known to determine which species belong to the genus or not, no
