The fact of the mutation may be very probable, but the full proof is, of course, wanting. Such is the case with the mutative origin of Xanthium commune Wootoni from New Mexico and of Oenothera biennis cruciata from Holland. The same doubt exists as to the origin of the Capsella heegeri of Solms-Laubach, and of the oldest recorded mutation, that of Chelidonium laciniatum in Heidelberg about 1600.
The oldest known, and at the same time one of the most accurately described mutations is the origin of the cut-leaved variety of the greater celandine or Chelidonium majus. This variety has been described either as such, or as a distinct species, called Chelidonium laciniatum Miller.
