Not all garlics can be classified neatly into any of the ten well-established varieties or may have traits of more than one variety but have not yet been taxonomically classified. These either didn't get traded along the major trade routes or were just remotely isolated for a long time. They are still good garlics and reproduce true to their own kind.
Every kind of garlic is unique in taste, flavor, secondary flavor and aftertaste. All of these unclassified garlics are unique in some ways that make them worth trying.
