Description
Rhipsalis bacciferaSN|6426]]SN|6426]] subs. shaferi is a tropical evergreen but leafless, succulent, epiphytic plant with thin hanging stems. Although a member of the cactus family, it has a very different appearence and is spineless. Subspecies schaferi distingushes for its generally shorter, stiffer stem-segments than subsp. baccifera, with which it intergrades. Subspecies schaferi, should be treated as a good species ( Korotkova 2011). It is commonly known as the mistletoe cactus.
