Need info on where to cut oncidium spent flower spike?

[greenpassion]

I know it's a little late, but I have two oncidiums (don't know which ones they are) but both have finished flowering. I cut the spikes close to the leaf joint, and all seems fine-but I realize now I have no idea if that was right. They are showing no sign of spiking since, and it's been about 6mths. These were given to me by two seperate friends who didn't care to keep them. I have never seen the actual flowers....
