Purple non-pulsing xenia

[FOREIGNER]

question...i bought a xenia tree last weekend and I have no idea what kind it is. It does not pulse, the color is between purple and dark pink with a thick and tall stalk. The polyps are long and at night the close up like a fist.

Interesting. Sounds like it could be a Cespitularia or Efflatournaria. Look here:
