Rhipsalis quellebambensis
''Rhipsalis quellebambensis'' is a member of the Cactaceae family and was first discovered by J. Mill Stearn in 1771. It is commonly called the mistletoe cactus and is often considered to be a synonym of ''Rhipsalis baccifera''.
==Epiphytic nature==
This species is an epiphyte and is found high in the canopy in areas with full sun in Central America’s rain forest. ''Rhipsalis quellebambensis'' favors deciduous trees over evergreen trees because of the better nutrient content of the soil produced at the nodes of branches on the trees. Deciduous trees though absorb less water in their bark as compared to evergreen trees which creates more water stress on the plant. ''R. quellebambensis'' has 36 other species in its genus and 1800 family members that can be found on almost every continent in environments that range from hot deserts, cold deserts, dry deciduous forests, and tropical rain forests. In the Americas, the Cactaceae family ranges from Alberta, Canada to the Andes in South America. Members of the ''Rhipsalis'' genus are more restricted and found only in the tropical regions of Central and South America. The closest relatives of ''R. quellebambensis'' are found in Brazil, East Africa, and the island of Madagascar. Only 10% of the related Cactaceae species are epiphytes making ''R. quellebambensis'' an unusual member of the Cactaceae family. In tropical rain forest though, epiphytes dominate the amount of Cactaceae species in a given area because it is the driest environment in the rain forest and where they have a competitive advantage.
