Yes, it's a cattleya - seems to be a cross between 3 of them, but I don't know which is the (presumably unregisterd cross) and which is the other parent - it is either:
Laeliocattleya 'Mari's Song' x [Potinara 'Love Call' x Potinara 'Jenner Gold']
or
[Laeliocattleya 'Mari's Song' x Potinara 'Love Call'] x Potinara 'Jenner Gold'
It's possible this is a registered cross, but without knowing which way round it is, it seems pointless to search
Also, the intergeneric name may be incorrect depending on what is in the background of these crosses (given the shuffling in and out of
Laelia particularly).
