Is it a dendrobium? And what kind?

[mtayl04]

I recently came into possesion of a plant that the person who gave it to me claims is an orchid. To me, this plant looks like bamboo, which would most likely make it a dendrobium...I think? The leaves though, are smaller and lighter in color than most pictures I've seen. They're almost a yellow green color. The tallest "stalk" is about a foot high. There are two others that are about half as tall, one which is brown and shriveled (dead, I would assume?) Does anyone have any idea what kind of orchid this is...if it even is one? I can post a picture if that would help.
