Polypiferus brevisimus

The bladder polyp is a simple plant with succulent leaves that grow in a mound directly on the ground. The larger teal-colored leaves store water in their tissues and are very attractive to animals for food. When the leaves are eaten or removed, new ones quickly grow in their place. (Read more)
The plant benefits from this sacrifice of leaves because animals that graze will leave droppings on and around the plant. Although most plants are unable to use raw manure due to its high concentration of salt and ammonia, the bladder polyp is a halophyte, meaning it has adapted to live in salty soils. The smaller brown leaves close to the ground are able to absorb high concentrations of ammonia. Salt accumulates in the larger succulent leaves, which causes the absorption of large amounts of water by osmosis, effectively diluting the salt.

Bladder polyp is eaten by the Na’vi for their juicy salty taste, which is somewhat like a pickle.
