In exchange for these nutrients, the black trees provide their symbionts with food. Only in the treetops, and in desert areas, do we find gelidephile plants that are not trees. We find pitchers like those of terrestrial pitcher plants, but with the function of collecting water, not trapping prey. Thermophilae Green plants quickly overshadow the snow-collecting pitchers of these gelidephiles in western Galgarok. To thermophiles on the savannah, the snow is a boon, ensuring a moist ground through most of the short summer.
Plants grow quickly to cover their gelidephile neighbors while the air is warm.
The host returns the favor by enveloping the vine with its own bark, for protection from herbivores. Pitcher plants by Carl J. Mazur, via the Carnivorous Plant Database .
