not sure what it is, but it looks very similar to odontocidium Niels Christensen, just the pics i've seen of the one named Niels C "Tow" have a more orange blotch on the center of th lip. it has four spikes. one larger one from the side of one buld, and 3 coming of another, one fromt he side, and 2 out of the top of the bulb??? i've never seen an oncidium do that, i thought they always flowered from the side? there is also a spot on one leaf of an older bulb that might have some sort of fungus, not sure, but it looks like a wet spot, and is sticky undernieth. keeping an eye out, and sterile scissors on the ready. this thing apears to be in moss, so i will repot asap, as i don't think an oncidium can take that long term in my care, even though phals do well for me in sphag.
