Catt identification

[ebi]

hi everyone

I'm a new to orchid growing and after doing some research on the subject i chose this catt from the local nursery. however it did not come with an identification tag- can anyone identify what cat this is? pseudobulbs are 21cm long, leaves 30cm , flower is 19cm across. any help would be appreciated.

here's a pic of it in bloom. hope it helps.
