Senecio and Furcraea are both a genus of what?
Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, "Senecio", means "old man."
Senecio gallicus Senecio gallicus, an annual plant of the "Senecio" genus and a member of the Asteraceae family is also one of those species who colonizes in isolated habitats where the environmental conditions could qualify as being difficult—widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. "S. gallicus" is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow.
