Ok .. here we go ...
First let's tackle Blc Bouton D'Or
According to RHS .. it is now called
Thwaitesara Bouton D'Or
=
Cattlianthe Wolteriana X
Rhynchosophrocattleya Buttercup
Thwaitesara (Thw.) is an hybrid orchid comprising of Cattleya,
Guarianthe, Rhyncholaelia and Sophronitis.
Cattlianthe (Ctt.) is an hybrid orchid comprised of Cattleya and
Guarianthe.
Guarianthe is the new name of 4 cattleya -
Guarianthe aurantiaca
Guarianthe bowringiana
Guarianthe patinii
Guarianthe skinneri
These have been separated from Cattleya based on phylogenetic studies with DNA sequence data.
Most but not all Brassolaeliocattleya are now
Rhynchosophrocattleya
So you have you are right with L. cinnabarina
So what you have is
Thwaitesara Bouton D'Or x L. cinnabarina
cinnabarina is lower case as it is a species laelia and not a hybrid ..
If you like I have the lineage to Thw. Bouton D'Or .. you can see how the genealogy ends up with species orchids with a few hybrids in between ..
