Dendrobium species ID needed

[Rosim_in_BR]

When I acquired it, the vendor assured I was getting Dendrobium alpinum. Tried unsuccessfully finding some image on the net that matched the flowers on my plant.
Has anybody seen this flower before? Any thoughts on what could it be? Hybrid, perhaps? The canes have somewhat prominent nodes, are thin at the base and pendent (they are artificially held up in the photos), the flowers, two or three at most, arise from the nodes.
I really have so much to learn about Dends, so any ideas would be helpful. Thanks in advance.

It looks like a hybrid of Dendrobium Nobile. I would try to search pictures of D. Nobile 'alpinum' and see if there is something like that. But I am pretty sure it is a Dendrobium Nobile Hybrid.

It is a Nobile hybrid, Rosim, but a very nice one at that.

Small consolation, I know, but I bought a tiny Dendrobium dearei 11 years ago, and it has only now flowered... turned out to be a Cattleya tigrina

I smelt a rat when the plant never developed more than 2 leaves
