Discussion
Senecio erucifolius has been introduced occasionally around seaports and has persisted. At present, it appears to be uncommon and highly localized; it should be expected almost any place that its close relative, Senecio jacobaea, occurs.
Senecio erucifolius was treated in Jacobaea by E. Wiebe (2000); see discussion under 53. S. jacobaea.
