<unk>  is a leafless succulent plant with cylindrical, green photosynthetic stems. The plant may grow as a shrub or a scandent vine. The stems produce copious amounts of milky exudate when broken. This exudate is caustic in nature and can cause burns if it contacts human skin. The plant produces small white flowers in clusters. Flowers are followed by long pods which produce numerous seeds with silky plumes that aid in wind dispersal. The environmental range of the species is very broad, extending from rainforest margins and monsoon forests to arid deserts. Toxicity appears to be variable, even locally. The plant is known to cause poisoning and death in livestock.
