Obesus rotundus - fat and round
|Behind the scenes|
The puffball tree (Na'vi name: rumut) is from the same genus as the puffer, puff daddy and vein pod. The tree is tall with globular structures supported by the branches. They are filled with hydrogen gas and sodium hydroxide, which can cause them to explode if provoked. The plant is very important in Pandora's eco-system, because of these structures. They absorb toxic gases like life-size vacuoles in plant cells. When they are large enough, they break free of the plant and float upwards. They also absorb excess sodium from the soil, and so the humans brought samples back to Earth, for potential use in areas where overfarming has left soils salty and useless.
Trivia[edit | edit source]
- In AVTR Advanced Team, puffball trees can be destroyed to make shortcuts in the map.
