If it were mine I would put a tag which said 'Phal. Sweet Memory (NoID)' or something like that. As Camille said in
this thread you can use a name of one it looks like and you think it
may be, just make sure your records are clear that it's not 100% and make sure if you post pictures you indicate that the ID is not 100% (otherwise others may ID theirs based on yours not realising it's not 100%).
I do this for ALL my NoID's. I find the closet match and use the name, or a variant of the name. For example I have one I call Kalaedoscope which may or may not be Baldans's Kalaeidoscope, I just always keep the NoID on the tag as well
