Thank you to occasional BPotD photo contributor Amir Auerbach of Israel for sharing today’s photograph via email. I’m making the assumption based on the file name of what he submitted that today’s photograph was taken in the Richtersveld area, a high desert landscape in the Northern Cape province of South Africa.
Aloe dichotoma, the quiver tree or kokerboom, is endemic to this area of South Africa (and neighbouring Namibia with its Namib Desert). Its common name of quiver tree is due to the species being used by the indigenous peoples for the production of quivers. These arrow-holding tools were constructed by hollowing out lengths of mature branches, then covering one end with a piece of leather. Dead plants of this species are also hollowed out and used as natural fridges for meat, vegetables and water.
The South Africa National Biodiversity Institute has an always-excellent article on Aloe dichotoma for additional reading.
