they can be of almost any colour.
Description: Very large and spiny cactus,
solitary or branched. The body is almost concealed by the spines.
This is a very variable species especially in shape and and length
of spines and in flowers colour.
Since the various forms
are connected by intermediates it is
extremely difficult to recognize
