I'm looking for the name of a particular species of tree. It's pretty tall but not thick, and it doesn't grow straight up, but branches outward. I don't think it has any leaves on it, nor do I think it has a trunk. It's white with stripes of black. I could have gotten some of the details wrong, since I'm calling all of this from memory, but if you could give me any information about this tree I'd be most grateful.
Edit: Thanks to your quick and informative replies, I now know that the species I was looking for is a white birch. Thanks again to everyone who helped me out with this question.
