Cattleya Popcorn is a registered hybrid, (intemedia x loddigesii) x loddigesii, and the flower does have the general look of a loddigesii hybrid. Maybe not impossible as a parent of this if the other parent is quite small like L. rubescens. So Laelia rubescens x C. Popcorn 'Confetti'? Or (L. rubescens x C. Popcorn) 'Confetti'?
And the plant, spike and flower look about right for a true Laelia x bifoliate Cattleya hybrid. Far from proof, but probably as likely as anything given the label.
