    Ok folks I think it is time to reveal the answer. But first let me tell you that all of you were correct in one way or the other, all flowers really do look different in different characteristics, but the main difference was that one of them was a hybrid while the rest were all different cultivars of the same specie. Another trick that was in the options was that actually there were two pics of the odd orchid from different angles and it seems the trick worked no one was able to identify that. So the final answer is L2 and R3 attaching the images again for the sake of convenience.

    These are the flowers of a primary hybrid, one which no one would be able to guess, it is Cattlianthe aurantiglossa (Cattleya amethystoglossa x Guarianthe aurantiaca), the reciprocal cross where Guarianthe aurantica is the pod parent, has very different looking flowers more like aurantiaca, but this one is a bummer looking more like the other which were all named cultivars of Cattleya intermedia. I start to question if there are really so many natural species or they just are natural hybrids that were created a few thousand years ago and now have stabilised in the population. Genetic studies such as these will be really fascinating.

    The second at the right side.
    This image is taken in a studio with black background.
    All other images are taken in the growing area in the middle of other plants.

    I can see a big problem on this game.
    The two images pointed out as Cattlianthe Aurantiglossa (Cattleya amethystoglossa x Guarianthe aurantiaca) are not Cattlianthe aurantiglossa!!!!
    They may have Cattleya amethystoglossa as a parent, They don't have Guarianthe aurantiaca as the other parent.
    Guarianthe aurantiaca is a orange or bright yellow species and this colors are dominant over cream and pink. Look at images of Guarianthe Guatemalensis. In not one of this so called Cattlianthe aurantiglossa we can see the lip shape of Guarianthe aurantiaca which is totally different.
    In my opinion this images show Cattleya Interglossa.

    Afert viewing for a long time and trying to compare what differences i might be seeing, I have concluded that the odd one out is R2 (middle right).
    The petals and sepals are different!
    Agree?

    Actually the colour of aurantiaca is not dominant, it is codomiant in case of guatamalensis, because you see a range of art shades some more towards skinneri some towards aurantiaca, but almost never the same orange as aurantiaca. But in other cases like Ctna. why not or anceps x aurantiaca the color is recessive, the flowers have the color of the other parent. The color is also recessive in case of Cattlianthe loddiaca (aurantiaca x loddigessi) where the colour are a solid purple like lodigessi, just soft lemon hints in the lip.

    Actually they are two pictures of the same flower from different angles. Yes the shape of the lip was of concern to me, but then again you look at the other aurantiaca hybrids like Ctna, why not, where no effect is seen, similarly there is a varying degree of its lip seen in Cattlianthe chocolate drop (Guttata x aurantiaca) with some clones like Volcano queen having much more guttata like lips. Secondly amethystoglossa is very dominant when it comes to lip characteristics with all hybrids that I have seen seem to have amethystoglossa like lips.

    Well after all these arguments, it very well could be another hybrid, we have to just take the word of the hybridizer, no one has performed genetic tests on this plant, but I think it is quite possible. Considering that it is a reciprocal cross of aurantiglossa (amethystoglossa x aurantiaca and not aurantiaca x amethystoglossa) it is possible for it to be more amethystoglossa like. Besides we have not seen all the siblings for this cross may be it was an odd ducking formed due to the unusual interaction of dominant and recessive alleles from both parents, other siblings could have been more aurantiaca like, we may never know.
