Notes for the Genus:
Rhipsalis
Rhipsalis are primarily epiphytic -meaning they live in trees, but some are lithophytic -that is growing in the cracks of rocks. This bulk of the species feature cylindrical-pendant stems that branch frequently, however some are flattened or have angled stems. Spines are absent in most or if present, very fine and hair-like. Flowers are among the smallest of cactus flowers if not the smallest and predominantly white; some may have a yellow or red tinge. Fruits on all are spineless except R. pilocarpa and are mostly pea-sized berries. There are just under 40 species and most occur in Brazil. A few are found more widespread in South America up into Central America, the Caribbean, and one species as far as Madagascar and Sri Lanka making Rhipsalis the only member of the Cactus Family that occurs naturally in the "Old World".
