Lost ID tag

[Cewal]

I’ve had this orchid many years, but lost the tag. Can anyone identify it?

Assuming it’s a species and not a hybrid, your best bet for a valid ID will not come until it flowers.

It has flowered many times. The flower is white and large, compared to the plant.

When it flowers, grab a photo. I am guessing that it is an Angraecum from the shape of the plant and those big knobby roots, with large white flower

It is an Angraecum didieri. I knew I would recognize the name when I saw it. Thank you so much.
