There are two subspecies of C. intybus. If you can identify any of these photos as C. intybus subsp. intybus or C. intybus subsp. spicatum or as cultivars of C. intybus, they can be moved to those entries. If not, then there's nothing to be done. External differences really are irrelevant. A cocker spaniel doesn't resemble a chihuahua, but both are of the same species.
