The throat looks different to the Remo Prada's 'on line'?
That's why it is an hybrid of it, and it cannot be a pure quadricolor species.
It is the same if I show a Paphiopedilum Delrosi. If I ask which known species it is, it can be said to be a brand new pink rothschildianum or a gigantic striped delenatii, especially if everyone believe it was wild collected or the true, guaranteed, progeny of a wild collected plant.
The plague in the Cattleya started in the 80s when many Japanese hobbyists and nurseries paid a fortune for a new color form of variety. As a result, many ' new varieties' and even species were 'arranged'.
That's how we got amongst others ' Cattleya motae' , a Brassocattleya, but the Cattleya motae was so rare that it sold for thousands of dollars to Japan, and the list is very long. Cattleya motae was wild collected in the jungle, with all the perils, and only a few plants were ever found. Fantastic fairy tale.
Many color forms of Cattleya are as well hybrids, so are many if not most of the walkeriana and nobilior. Some Brazilian nurseries became expert in screening what looks too much hybrid, the same for Paphiopedilum godefroyae and leucochilum. It is very rare too that people buying a ' top quality rarity' self and flower the seedlings, so the risks are limited for Cattleya.
But for that quadricolor, the flower has nothing to do with the species, aside from the fact that it is a Remo Prada hybrid, typical for the color pattern as well. They were produced, and sold from Brazil as various new rare flare wild collected species of various species about 15-20 years ago.
