This Senecio hybrid was growing together with S. squalidus in the gravel of a railway siding. I couldn't find any other Senecio species. Photo 1 (hybrid on right), Photo 2 - leaves + capitula (hybrid at top), Photo 3 - capitula (hybrid on left), Photo 4 - leaves (hybrid on bottom), Photo 5 - capitula + seeds (hybrid on right).

Seeds don't look viable, in contrast to seeds of S. squalidus.
