Vein pod
VärumutThe vein pod is related to the puffball tree and puff daddy, all of which are considered keystone species on Pandora for their important role in maintaining stability of the environment. The globular balls produced at the tops of the vein pod trees and ends of the branches act as sponges, absorbing methane from the atmosphere. Because of their ability to sequester methane, these plants emit a strong foul odor and are usually avoided.
