When two species hybridize that’s considered a primary hybrid, or according to the botanical standard, a notho-species. Beyond that, a third species onto a primary of two other species, makes a complex hybrid. So really it’s anything where 3, or more, unique species are in the background. If an original parent of a primary hybrid is crossed back onto the primary hybrid, it retains the same notho-species name. That’s not helpful to Orchid hybridizers and other who track genealogy. So they make a distinction between a primary hybrid and its backcross progeny and tend to avoid the notho designation except in the case of natural hybrids.
