Has anybody any idea what kind of cactus this is? I "found" it growing in Spain and snapped off the branch you see at the bottom.

It is growing air roots all the way up it, so I assume it is a type that hugs a tree.

I don't know why it keeps going thin, it is one stem not a load of short connected stems.

It´s some kind of epiphytic cacti but it´s impossible to give it a name. To get a chance to name it you must take a photo of the flower and even then it´s hard to tell. There are so many...
It can be an Epiphyllum but´s there´s a millon hybrids to speculate about. Here you can se some: http://www.epiphyllumsociety.org/pentic ... t/pic.html

Give the plant a little bigger pot and well drained soil. They like to spend the summer outdoors. You can hang it in a tree, semi-shade is perfect and it can stand the rain as long as the pot has a lot of holes so the water don´t stay. Good luck!

After a few days of thinking... Your photo reminded me of something I had earlier. If it´s a very sticky plant, it could be some type of Hylocereus.
I had a Hylocereus undatus, comes from Thailand and gives a fruit called Dragonfruit or Pitahaya.
Got rid of my plants because they growed so fast and took a lot of space.
Here´s some info about Hylocereus: http://www.desert-tropicals.com/Plants/ ... ereus.html
