Senecio cambrensis

''Senecio cambrensis'' (Welsh groundsel or Welsh ragwort) is a flowering plant of the family Asteraceae. It is endemic to the United Kingdom and currently known only from North Wales. It is a recently evolved plant which arose suddenly as a result of hybridization between two related species.
==Origin==
Welsh groundsel is an allopolyploid, a plant which contains sets of chromosomes originating from two different species. Its ancestor was ''Senecio × baxteri'', an infertile hybrid which can arise spontaneously when the closely related groundsel (''Senecio vulgaris'') and Oxford ragwort (''Senecio squalidus'') grow alongside each other. Sometime in the early 20th century, an accidental doubling of the number of chromosomes in an ''S. × baxteri'' plant led to the formation of a new fertile species, Welsh groundsel.
