Aloe dichotoma, also known as quiver tree or kokerboom, is a 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 name from their practice of hollowing out the tubular branches of Aloe dichotoma to form quivers for their arrows.[citation needed] As of May 2011, the World Checklist of Selected Plant Families recognizes three subspecies, A. dichotoma subsp. dichotoma, A. dichotoma subsp. pillansii and A. dichotoma subsp. ramosissima. These have also been treated as three separate species, A. dichotoma, A. pillansii and A. ramosissima, which are then grouped within the Dracoaloe subsection of the genus Aloe. All inhabit the same arid areas of the Richtersveld and the Namib Desert around the South African-Namibian border. Treated as separate species, the three have been given different ratings on the IUCN Red List of Threatened Species: 'vulnerable' for A. dichotoma, 'critically endangered' for A. pillansii and 'endangered' for A. ramossisima.
