Saltarus pendulus

The beanstalk palm is named for its ability to grow to exceptional heights in the dense atmosphere and low gravity of Pandora. When it is young a tree provides shade and its leaves can be harvested for their fibrous tissue. They are used to weave mats, baskets, banners, and bridles and saddles for direhorses. Unlike its relative the razor palm, the beanstalk palm has rough but not sharp bark and is easy to climb. Birds and small climbing animals are often found nesting in its canopy. (Read more)
Once a tree matures, it continues to grow to heights not seen on earth, which places the canopy above most other trees on Pandora. Those not afraid of heights can climb to the top, although on windy days the trunks flex and sway and climbing can be dangerous. The leaves can be used to make a harness to hold the climber onto the tree during the ascent. The Na’vi use the taller trees as lookout posts and launching sites for banshees.
