This sub-tribe contains many interesting plants They develop many-branched stems, and in their natural environment they are found growing on trees, or on the ground, in rocky places, from which they hang down. The branches or joints may be cylindrical, or flat and leaf-like, or angular. The spines are mostly absent. The flowers are small, and the berries which are produced are usually the prettiest decoration of the plant. They are white, red, or purple.
