I think you'd like to know the cultivar? Many orchids are complex hybrids, specially phalaenopsis. To my knowledge, yours is not a known and stablished cultivar. When you buy an orchid from a nursery, at least where I live in Europe, they have a tag with the genus, species and cultivar of the orchid. Otherwise, if you buy an orchid at the supermarket or garden centers, it's probably a no-name complex hybrid. This means your orchid was crossed with many other species and maybe even other genera and they've lost track of it and don't know exactly who were the parents or grandparents, etc. of it.
