I recieved this plant about a year ago off of Ebay as a D. intermedia, but having seen pictures of intermedia and nidiformis, I'm beginning to believe otherwise. Here are a few pictures of it.
Here is a representative picture of intermedia 'cuba'.
And here are three pictures of nidiformis leaves.
And here is a picture of a nidiformis plant with a curling flower stalk.
The flower on my "intermedia" didn't have spaced out bud-looking things like on the picture of the intermedia 'cuba', but instead was curled, and unfurled like a capensis flower stalk, and the flowers were pinkish purple.
After making this post, I'm now pretty darn sure I have a nidiformis. Oh well. At least no dormancy.
Certainly looks like a nidiformis, it could be a hybrid I suppose.
