Ray’s record refers to Tordylium officinale, but Morison’s plant is T. 
maximum, a8 was also the plant from the Parks shown to Woodward, vide 
With. ed. iv. p. 365. Miller states that he found 7. oficinale growing on 
sides of banks in Oxfordshire, but adds ‘the seeds were sown by Jacob 
Bobart, gardener at Oxford.’ I have little doubt that Miller was mistaken 
in referring the Oxford plant to officinale. He was probably correct 
in suggesting or stating that Bobart planted it about Oxford. Most likely 
we owe Senecio squalidus to the same individual. Tordylium appears to 
have been found from 1696 to 1821.
