We have no separate entries for unidentified hybrids of a particular plant species, and our species entries are not confined to the "true" species. A photo of a plant that is a hybrid of two known E. huascha cultivars, for example, could be added to the E. huascha entry. In this case, however, because the parentage is unknown, I would agree with jmorth that they should be added to the generic Echinopsis entry.
