Common names
This plant is commonly known as the "Halfmens," which means "half-human" in Afrikaans, referring to the plant's peculiar, human-like shape. It is also known as the "Desert Bottle Tree," "Kokerboom," "Quiver Tree," or "Aloidendrum erosa," a previous scientific name.
Appearance
The Commiphora erosa Vollesen plant is a slow-growing tree that reaches a height of 4-7 meters, with a trunk diameter of 30-60cm. It has a thick, cylindrical stem or trunk, which is covered with a bark-like tissue that is smooth and shiny on the outside. Its branches and stem are thorny, making it difficult for animals to feed on its foliage. This plant does not have leaves; instead, its branches are lined with fleshy, succulent stems, which can photosynthesize.
The Halfmens tree is unique and recognizable because of the peculiar shape of the stems. It looks like a human, with its thick trunk resembling a torso and its branches outstretched like arms. It can produce flowers that are small, white, or yellowish-green, which bloom in clusters during late winter or early spring in South Africa.
Uses
