Flaska reclinata

The Baja tickler resembles no plant growth form on Earth and is unique on Pandora. It has been described as something like a large hollow tree that usually grows at an incline. A cluster of large spiny leaves adorn the top, and large roots extend out from the underside of the stem, which grow to the soil and help anchor and prop up the plant. The surface is rough and green due to a dense covering of small moss-like plants that can withstand high temperatures and harsh conditions. (Read more)
The Baja tickler is one of the most important plants on Pandora. It is also one of the most dangerous. It plays an important role on the moon by helping to detoxify the atmosphere. Toxic gases (mostly volcanic in origin) are absorbed into the plant body where they dissolve into a pool of watery liquid that accumulates inside. This primeval “soup” periodically builds up pressure and temperature and is squirted explosively in a toxic plume from the top of the plant. The Na’vi recognize both the value and potential danger of the plant and mainly avoid it.
