Not sure what kind of an Oncidum it is. Someone gave it to me with no ID on it. It does like to bloom though and right now it has five stalks (about 3' high) and full of buds. These pictures are of one of the first flowers to bloom. The last time it bloomed, in early April 2006, the flowers lasted till early August. The first one is a 30% crop and the second is full frame.
