Thanks for the information about gordlinia. It is not findable by searching the database for gordlinia. Would it be possible to have these intergeneric hybrids be findable by their "cross" name without the "X"? I don't think most gardeners consider the "X" to be part of the genus name.
Also, would it be possible to include hybrids of two species in the database by referring to their two parents, when the "named version" of the hybrid is not considered valid? On my PlantLinks site, I extended the use of subsp./var./forma subtaxons to also accommodate such cases, as exemplified on this page:
