have you seen this plant bloom before? How old is it? How's the air movement, is it getting enough? I know plants don't "shake" open in the wind, but if it's dead stagnant, I would think that would have some impact on development of flowers. How are the leaves and psuedobulbs?
It could be a genetic defect, otherwise it could be conditions aren't what it likes?
