Giant Groundsels on Mt. Kilimanjaro (Prehistoric Plant)

In order to carve out an existence in such a forbidding environment—that high up the mountain, temperatures regularly dip below freezing overnight—the plants have evolved water storage in the pith of the stem, nyctinastic leaf movement (which means the leaves close when the temperature drops too far), a natural “anti-freeze,” and self-insulation through withered and dead foliage (part of the reason the groundsels look so strange).
