Catasetum Weirdness

[isurus79]

Honestly, I think the large bulb is rotting so I'd cut it off and tie down the cut-off bulb horizontally so that the new growth will grow into a pot. When you cut the bulb, you'll see brown parts. Be sure to cut that back until there is no brown, only green.

The overall plant looks like it was not grown well during the active growth season. Cat tenebrosum has big fat p-bulbs and the fact that yours are so skinny makes me think it wasn't grown well for quite some time now.
