Keep the Winged flight tag, and put it as hybrid anyway, no one will ever know if it could have been a lowii, even the most skilled taxonomist. Only DNA analysis could get a result for that plant.
Winged Flight is 75% lowii, and typical of a VERY stupid and dangerous hybrids, in the line of malipoense x jackii or many brachypetalum fake species.
And I see that Orchid Inn even has Winged Flight x lowii, which will be nearly like a pure lowii (87,5% lowii!), but with longer petals. That kind of crosses should be definitely banned.
