Any clue what type of Dendrobrium this is?

[Sweet Dee]

I've been told this is a dendrobrium, but am wondering what specific type it is. The plant has lost many stalks and has not flowered in eight months (which is unusual for it, as it usually flowers every three months). I'm hoping to learn more about it so as to better care for it. Any clues as to it's identity or care are helpful. Thank you.
