( Senecio cineraria DC. ):

2« = 40. Rocky and sandy places. W. & C. parts of Mediterranean region.

The plants widely cultivated for ornament and locally naturalized in W. Europe correspond to subspecies (c) in some respects, but vary greatly in the distribution of leaves on the stems.

Plants from the Kikladhes (Amorgos) with very broadly ovate, strongly lyrate leaves and glabrescent involucre, but otherwise like subsp. (a), may represent another subspecies.
