Description

A small, low, spreading, semi-geophytic stem-succulent, with tuberous roots and rhizomes. During the dry seasons, the stems can die back above ground. The stems are somewhat segmented. Each branch is rounded-to-cylindrical, but at its point of growth it is constricted. The solitary cyathia are carried on short peduncles. Their five involucral glands each carry 3 or 4 distinctive finger-like outgrowths.
