Please help me identify this long aerial root vine

Anybody please help me identify this long aerial root vine.
It has been grown in Thailand for a long time but I am unable to find its scientific name.
It's a very popular vine for tropical and Bali gardens.
Anyone know the name?

Thank you very much.

Dioscorea perhaps?

 

Thank you Saltcedar. I'm not so sure if it's Dioscorea. As far as I know this vine doesn't have any tuber. But I will look closely if it really belongs to this family.

 

Cissus sicyoides (Cissus verticillata )"Curtain Ivy" or "Princess Vine"

Beautiful! A living curtain---wow. Cool. Whatever it is.
Are we sure that the leaves visible belong to the plant producing the roots? That there is not another plant thriving on top or alongside the curtain-maker?

 

Thank you very much Saltcedar!
That's very quick for the name of this vine.

 

Definitely, the roots and the leaves are from the same plant. The roots can create beautiful visual effects in the garden!

 

Amazing! How much maintenance do they require---must they be "combed" to hang so neatly, or do they just grow that way?
