Hard to say with just that info. What's the specific cross? It depends on whether the B in Blc is truly a Brassavola or Rhyncholaelia. Some Blc's really use only Brassavola, some only used Rhyncolaelia, some might even use both.
B + C + L + S = Potinara (Pot)
Rl + C + L + S = Ankersmitara (Akr)
if the B is Brassavola, then it's Blc x Pot = Pot (same parent genera)
If the B in Blc really was Rhyncolaelia, then Rl x L x C = Rhycatlaelia (Ryc.)
That would change the genus (new parent genera). Ryc + Pot = Wrigleyara (Rl + B + C + L + S)
And this is assuming one of the Cats used wasn't' really Guarianthe.
