Lepismium species

Lepismium species;

Succulent from Hortus Botanicus Leiden: Could you help me to ID the following hanging plant please.
Probably some species of Bryophyllum but I not very sure
Could this be a species of Christmas or Claw cactus? Are the round objects fruits? In Christmas or Claw cacti flowers are usually apical.
I think this looks like a Cactaceae, may be some species of Epiphyllum.
This is a Cactaceae and most probably some species of Lepismium.
Thanks ... It does look like Lepismium from the web photos.
NOT christmas cactus of any variety for sure... though I am not sure what it is... I only know what its not...
