PK Comments
Ritter's 'var. nuda' was not taken up by other
authors. In habitat it is possible to find the occasional spineless specimen,
not just of C. columna-alba, but of most Copiapoa, especially
those of the Cinerea group. This includes normally spined plants, with
spineless off-sets, or plants that seem to have experienced a period of growth
during which spines did not develop.
I am not aware that this feature comes true from seed.
