Disocactus amazonicusSynonym: Wittiocactus panamensis, Wittia amazonica, Wittiocactus amazonicus, Wittia panamensis
This is the only Epiphytic cactus I have, most get way to large. Just love the pink tubular flowers, with bluish tips that barely open.
Scale and mealy also loves this plant. Scale, I think love it the most I have to always keep my eyes open to keep them off.
