It looks like it could have Schomburgkia superbiens in it. But usually an untagged orchid can not be properly identified. It is only just a guess. We call them NOID's and love them for their beauty even without a name.
It looks to have a lot of intermedia in it. But that can depend on how tall or short the pbulbs are. These look like my intermedias although the lip is not as long here. There are so many hybrids with flowers almost identical.
