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 evolutionary 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 be released from the top of the tower. Some species feature external rings that can be used to gauge an organism’s age.

Due to their fragile structures Tubus prefer open plains but are tolerant of light undulation, low-lying rocky protrusions or the lowest levels of gentle slopes .

Tubus Compagibus

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.

Tubus Conifer

A Tubus Species formed from hollow vertical cylinders that can reach heights of six metres. Mature specimens are capped with a downturned crown that can distribute seeds on the wind across a wide area.

Tubus Rosarium

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.

Planetary Body Type: Rocky
Atmosphere: Ammonia
Volcanism: Low numbers existing on planets with mainly particulate Volcanic activity. Potentially indicates tolerance rather than preference.

Tubus Sororibus

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.
