Description
Pseudorhipsalis ramulosaSN|8613]]SN|8613]] (also known as Red mistletoe cactus) is a graceful shrubby epiphyte succulent freely branching basally with completely pendant flat reddish tapeworm stems and the more sun, the deep violet red it gets. It produces lots of greenish-white flowers followed by small mistletoe-like fruits lining both edges of the ribbon stems most attractively. It forms large hanging clusters. Two subspecies are recognized, the nominate form and subsp. jamaicensis (Britton & Harris) Doweld.
