My best guess is
Encyclia hanburyi, or a hybrid of it. The main difference I see is the sepal and petal striation lacking, and the side lobes of the labellum are brown. I think I have a variation of
Enc. hanburyi that it close to what yours looks like. It is in spike now, and will bloom in a few weeks.
Can you post a picture of the plant?

Still a very nice plant, the flowers look attractive and plentiful!
