Tubus genus
Description
Highly specialised organisms that can grow to extreme heights, which peak when in a mature state. The organisms’ height and ability to survive is largely constrained by gravity. The lack of any real atmospheric weather has not put evolutionaly pressure on the towers to be strong, so they form tall but thin structures which cannot be supported in high-gravity environments. The tower is formed from wrapped leaf-like structures, which create a regulated chimney void. This is used by the organism to create and maintain an artificial internal atmosphere, where discrete chemical processes can be undertaken along the length of the tower. Waste gases and other material may he released from the top of the tower. Some species feature external rings that can be used to gauge an organism’s age.

Tubus cavas

Description
A tubus species that extends pale vertical stalks composed of rigid modules. Colourful fronds frequently appear in the gaps between segments and aid with controlling gaseous exchange.
Conditions of occurrence
- Planets with thin Carbon dioxide atmosphere
- Rocky planets
- Maximum gravity: 0.15
- Mean temperature between 160 K and 190 K
Colored variants
Colored variant determined by the parent star type (see above, genus Tubus)
Tubus compagibus

Description
A tubus species with narrow pale segments and fronds growing between each module. A wide crown of leaves at the peak hold spores on their undersides, to germinate across a wide area.
Conditions of occurrence
- Planets with thin Carbon dioxide atmosphere
- Rocky planets
- Maximum gravity: 0.15
- Mean temperature between 160 K and 190 K
Colored variants
Colored variant determined by the parent star type (see above, genus Tubus)
Tubus conifer

Description
A tubus species formed from hollow vertical cylinders that can reach heights of six metres. Mature specimens are capped with a downtu rned crown that can distribute seeds on the wind across a wide area.
Conditions of occurrence
- Planets with thin Carbon dioxide atmosphere
- Rocky planets
- Maximum gravity: 0.15
- Mean temperature between 160 K and 190 K
Colored variants
Colored variant determined by the parent star type (see above, genus Tubus)
Tubus rosarium

Description
This tubus species is composed of squat tubes growing into a vertical spire. The upper pods of mature specimens produce explosive seed pods on their outer skin.
Conditions of occurrence
- Planets with thin Ammonia atmosphere
- Rocky planets
- Maximum gravity: 0.15
- Mean temperature superior to 160 K
Colored variants
Colored variant determined by the parent star type (see above, genus Tubus)
Tubus sororibus

Description
This species of tubus grows a cluster of hollow stalks composed of rigid segments. Over time these become capped with a growth that flowers and produces seeds.
Conditions of occurrence
- Planets with thin Carbon dioxide or Ammonia atmosphere
- High Metal Content planets
- Maximum gravity: 0.15
- Mean temperature between 160 K and 190 K
