[9] M. A. d'Orbigny (vol. i. p. 474) says that the cardoon
and artichoke are both found wild. Dr. Hooker (Botanical
Magazine, vol. iv. p. 2862), has described a variety of the
Cynara from this part of South America under the name of
inermis. He states that botanists are now generally agreed
that the cardoon and the artichoke are varieties of one plant.
I may add, that an intelligent farmer assured me that he had
observed in a deserted garden some artichokes changing into
the common cardoon. Dr. Hooker believes that Head's vivid
description of the thistle of the Pampas applies to the
cardoon, but this is a mistake. Captain Head referred to the
plant, which I have mentioned a few lines lower down, under
the title of giant thistle. Whether it is a true thistle I do
not know; but it is quite different from the cardoon; and more
like a thistle properly so called.
