In the middle of a near barren Namib Desert, looking like a fishing net with floats entwined, bitter Tsamma melons (Citrullus ecirrhosus) or Namib tsamma, a species of perennial desert vine can be found growing in the baked earth.
It is a gourd, and can be found in Namibia and South Africa, but particularly the Namib Desert.
It can be a vital source of water and when cooked can be eaten. There are sweeter varieties.
