Quiver Tree

"is one of the most distinctive elements of the flora in the Northern Cape and Namibia, where it rises from the scrub and desert on ancient trunks with an unmistakeable crown of leaves. It takes its name because the native San Bushmen used the dead hollow trunks as quivers for their arrows. Apparently dead trunks are also used as natural fridges; as the fibrous tissues cools the air as it passes through it, making it a useful storage space for meat, vegetables, and water." The species is considered greatly threatened by climate change. "The rapidly changing climate in Africa means Quiver Trees are slowly losing the populations on the equatorial limit of their range, while by contrast the plants are flourishing pole-wards. However, IUCN report that no new populations have been found in their pole-wards range and worry that eventually the climate will overtake the plants leaving isolated populations, with no recruitment, to simply die out."
