Another plant I'm contributing is from southwestern Morocco and the Canary Islands. It's variously called either Caralluma (the older name) or Apteranthes burchardii. There's a nice snippet about it here. Like the Stapelia or Carrion Flower that I am also contributing, this is one of what I call the stinking milkweeds. That is, it's a succulent in the milkweed family with fleshy stems, no leaves, and grows in very dry areas. Unlike the giant carrion flower, this has clusters of many minature flowers at the tips of the stem in early summer.
