Rhapsus excelsa help!

[AL_SFBay]

Hi everybody I am a noob to this forum but have had this 12' Rhapsus excelsa "Lady Palm" for many years and she is now pretty  root bound.  I was getting ready to repot but I had to wait till I moved as the shock would be huge.  The light in the 2 different places were hugely different. In the meantime, while I was waiting to move it and have it adjust to the new location these funny green things grew.  Being an epiphyte lover, I thought they might be air roots.  but they stay green unlike the Rhapsus air roots.  This plant blooms regularly and was very happy in its old SW window with indirect light.  She is now settled in a E facing window and is doing well but it is time to repot.  Before I do it I wanted to know what to do with these green things!  Also I was planning on cutting the tall trunk off as it is hitting the 12' ceiling.   should I wait till it settles after the repot?

Here are a few pics.    All advice is welcome

Those grassy growths are not part of the palm , at least I’ve never seen anything like that growing out of a Rhapis palm. Your palm looks healthy and I wouldn’t worry too much about the change in location , as long as it gets bright , indirect light. I would remove the grassy stuff when you repot it . To me , your palm looks more like a Rhapis Humilus than Excelsia . The pointy leaf tips are not typical of Excelsia that usually have blunt , toothed tips. Harry

You can see the tips are blunt and toothed. I hope this helps. The Rhapis Humilis , which is what I believe you have , would come to a point at the tips.

Harry thank you for identifying it, I can ID orchids, not palms!  the reason I thought it was Rhapsus excelsa was when it flowers, it looks like pictures I've seen online of Rhapsus excelsa blooming.  

Have you ever seen growth like that?  I have dug around as best as I can and I thought it was from the plant but it is so root bound I won't know until I repot.  That growth is not grassy.  All that growth is needle-like.  

I would like to terminate the tall trunk as there are several buds on that rhizome.  Wouldn't this stop the height problem and increase lower growth as in a new shoot or two?  The question is do I do it during repot or wait a bit.

You can cut the tall stems out of the clump at any time . The long petioles are because of low light. The more sun it gets , the shorter the petiole will be . New stems should continue when it gets in a larger pot.  Harry

Thanks for your quick response.   I was worried about shock if I cut a major stem and then transplant it.
