Which of the Southern African trees listed is shown in the picture?

The tree shown is “Aloidendron dichotomum”, formerly “Aloe dichotoma”, the quiver tree or “kokerboom” (in Afrikaans), is a tall (up to 9 metres), branching species of succulent plant, 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 English common name from the San people practice of hollowing out the tubular branches of the tree to form quivers for their arrows. The specific epithet "dichotomum" refers to how the stems repeatedly branch into two ("dichotomous" branching) as the plant grows.

The tree is listed as “Vulnerable” by the IUCN (International Union for Conservation of Nature), being under threat from climate change. Like all aloes, quiver trees are succulents. They store water in their stems and leaves, have smooth bark and gray-green leaves and bloom during the winter season, in June and July. The flowers are yellow.
