This plant has a stem reminiscent of cacti but has no areole. It is a succulent endemic to South Africa.
The stem is four-cornered, and the area between ridges is deeply dented.
It has coarse teeth on the ridges at long intervals.
The bud is larger than a chicken egg, and has a red tinge before opening.
The bloom is dark purple and starfish-shaped, and can be around 15 cm in diameter.
It has a small light green calyx. The petals have lateral creases and flexible hairs which are longer at its edge.
The corona is double and split into 5. The inner corona, which encloses the gynostemium, projects out
from the center of the flower and is a-shaped. There is an outer corona which is small and petal-shaped.
The white part at the center is a stigma, and the yellow parts around it are pollen masses.
When opening, it releases a carrion odor to attract greenbottle flies to lay their eggs,
and the resulting maggots mediate pollination.
