I think it's safe to assume that it'd be very difficult for anyone to give you a specific name on this particular kind of orchid.
The only thing anyone can tell you with great certainty is that it is:
1. A Dendrobium.
2. It's a hybrid.
3. It's a cross between a Den from section Phalananthe and a Den from some other section in which even with a picture of the flowers would be very difficult to recognize.
4. And like Kiki said is a Dendrobium of the beautiful kind.
Dendrobiums can be a bit tricky to master growing because a few of them have periods of dormancy, but a beginner could easily learn which Dendrobiums require a rest period and how to successfully grow them.
