Aloe dichotoma (the quiver tree or kokerboom) is a tall, branching species of aloe, indigenous to Southern Africa, specifically in the Northern Cape region of South Africa, and parts of Southern Namibia.
Known as Choje to the indigenous San people, the quiver tree gets its English common name from the San people practice of hollowing out the tubular branches of Aloe dichotoma to form quivers for their arrows. The species name "dichotoma" refers to how the stems repeatedly branch into two ("dichotomous" branching) as the plant grows. Wikipedia
