Actually it is andreettae x pearcei!
It is a flask that I found in a back bench of our lab... If you look at it carefully you will notice that the bigger plant is branching itself several times and a new growth appears on top of each leave and even it develops new roots, almost like a vanda!
I guess that this behaviour is because the high hormones content in the growing media... but the other plants developed normally... lets wait to see what happens here...
