Hi Salamandra; this doesn't seem to be a popular plant at all, there is no picture of it in OrchidWiz, and this cross has only one registered subsequent cross (with
Brassavola martiana, yielding Bc. Nube de Oro). Considering Intebrosa was registered in 1950 and the other in 1969, it seems not to be something with overly loved flowers that hybridisers saw potential in. I guess we'll have to wait and see what yours yields if you decide to cross it!

I'm actually quite surprised that I can't find something like
Paphiopedilum Primary Hybrids for cattleya primary hybrids, but I guess the Cattleya fans have better things to do than mucking about on the internet, unlike the slippernuts.
