Hi Bill, I really don't know much about orchids at all and it seems names are changing all the time! When I got this one in 2009 it was labeled Laelia purpurata x Bl. Richard Mueller; then at some point, I was told the name had changed to Brassolaeliocattlya then not long ago someone said it is now called Brassocattleya 'Sunset Glory'.
Our database shows parentage as:
Richard Mueller X Cattleya purpurata
We have this one in our database that kinda looks similar:
