Psuedolithos migiurtinus is a rare succulent endemic to eastern Somalia. It is one of the most unusual members of the Asclepiadaceae family, with highly succulent stems patterned with irregular, rather warty looking, hexagonal tubercles giving this plant the appearance of a curious, rough stone. It is quite variable in shape, color and size. This species is likely the most popular in cultivation. These plants produce carrion flowers which are generally fly pollinated, as the blooms often smell like rotting meat.
