Astistok is a species of small, leafy flora found to have sprouted up after the end of the glacial age of the planet Zukabergo-Nama Gusuk related to both the Zukabergo Blackleaf and Redleaf. They notably only sprout up out of specific mineral deposits, which are named after the plants: Astistokite.
Like other "new" floral species found on Zukabergo, Astistok produces a large quantity of seeds in preparation of the prolonged glacial period to come. Astistok, like both Blackleaf and Redleaf, produce their seeds from tubers formed from their roots, thus shoving their seeds deeper into the substrate for easier survival. These seeds can remain dormant for at least ten thousand years before the next irradiation period.
However, unlike its cousins, Astistok requires Astistokite to live; when the irradiation overtakes the planet, it causes a chemical reaction in Astistokite that releases the necessary nutrients for Astistok seeds to germinate. However, with each subsequent generation less and less of the mineral exists as they use a minuscule amount for each sprout. In other words, the mineral is slowly eroding away. It is believed that eventually all of the mineral blocks will be eroded and at this point it is not known whether the Astistok will go extinct or will have evolved to a point by then to subsist on the broken down bits of the mineral within the surrounding substrate. Either way, this will still take millions of years before this will come to fruition and is not considered an "immediate concern" by any of the species involved in their research and study.
