Catt rhizome growing at vertical slant - help with repotting placement?

[cythaenopsis]

I have a related question about rhizomes, so I hope it's OK to put it here rather than starting a new thread.

I have a small Cattleya (Sierra Skies Leone) and I'm trying to understand what part of the plant is the rhizome. I'd thought that this was a synonym for the pseudobulb, but from what I've seen on-line it's what the pseudobulbs sprout from. Unfortunately, I've not yet found a clear description and/or photo to illustrate it. On my plant, the pseudobulbs extend from the center of the plant, but I can't make out what's there. Below are some photos. Can someone point it out? Thanks!




Note that there is a little wet moss still tangled in the inner root cluster here. I had taken the plant out to put in new potting mix.

The rizome on this is so short as to be impossible to point out. But it would be the portion between the pbulbs if it were longer. As this plant grows you will be able to see it. Use tweezers to get the moss out from within the rootmass. Cut off those grey rotting roots and dip the whole rootmass in peroxide then wash off and pot.

In general it's where the root are coming out of the plant.

with the l being the psuedobulb, and the_ being the connecting tissue.....however short the connecting tissue is, its still there to some degree, and this is called the rhysome.....hope this helps, gl
