You were unable to find Gordlinia because I had just created those entries and it takes a while for them to be included in our search data. That's why I gave you the link to all of them. You will find it now, with or without the "x."
As for your other question, if you mean something like this entry on your site, then I have to say that we have never included entries of this type and probably never will. We don't list unnamed hybrids. We do list the accepted hybrid taxa.
