Wow! That is a massive P. ridleyi! They are well known to be difficult to keep. If they lose their apical growing point, they rarely recover and produce another growth point. They are related to the P. coranarium, in that they both produce paddle spore pads, the only two species of the group to do so.

I have a 10 yr old P. superbum, and a form of P. bifurcatum, cv. hillii. I'll try to post a pic of them soon. - Rich
