This seems like it would be an epiphytic orchid - is it a dendrobium? It was left at my apartment door (for no reason!) a few years ago after it hadn't bloomed for a year or two, and this is the first time it's flowered since I've had it. All I know about orchids is the names of the two others I have, so I may as well seek some sort of id for this one. The buds turned dark at the pointed tips before they opened, and I was afraid they were dying from lack of water, but now I suppose that's just the way they grow.
