Is this some kinda Paph.

I got this plant-with just 2 leaves from a plant nursery from where I buy non-orchids and saplings. The owner who was my patient gave this free as a token of goodwill. He described it as rare, precious, restricted ....slipper orchid. I have been growing it for the past 4 years...no flowers yet. What should I do? Medium- charcoal, broken bits of terracota and bricks.
