Remarks : |
After a morphological and molecular study on the Jacobaea maritima complex, it was found that the Maltese plants (formerely known as Senecio bicolor) are different from the other Jacobaea species or subspecies; therefore described as a new taxon: Jacobaea maritima subsp. sicula. This subspecies is also and only found in Sicily and its islands and so this plant is a endemic to Sicily and Malta (subendemic to Malta). It is protected by regulation 26 of legal notice LN311/2006 |
