NoID Cattleya

[Nokomis.FL]

Someone brought a giant heirloom orchid to the orchid society meeting in February or March and divided out about half the plant. It had a broken tag that I'm told looked like 'C. marr..' before the break. Seems I'm the first to have gotten a bloom. I'm now thinking that the tag actually said 'C harr' and that this plant has C. harrisoniae or C. harrisoniana in it. Any ID or help will be greatly appreciated.

Edit: So far two people on the Florida Orchid Growers Facebook page think it's got C. harrisoniana in it, but some cross.

is it a bifoliate? It more likely is a cross. The lip doesn't look quite right.
