Water! What Are The Main Water Holding Plants?

I am new to this but I am kind of wondering about finding water in the wild all over the world. I want to be mentally prepared.
Can anyone with exp help me out?
What all are the plants and vegetation, that I need to keep in the back of my head at all times, that provide drinkable water ?
Is it a short list?
Happy surviving.

 

You might be referring to the plants known as "succulent plants". They are literally plants that can store big quantities of water.
There are actually a lot of them, like the agave plants or most of the cacti plants.
But there are a lot more: you can find plenty of useful lists around the web (Wikipedia have an entire article about them) that might help you out.
