Notes

As explained under Hatiora, the inclusion of Rhipsalidopsis in Hatiora is not supported by recent molecular phylogenies. Calvente & al. (2011) found the two traditional Rhipsalidopsis species (R. gaertneri and R. rosea) as sister to Schlumbergera, but with moderate support. Korotkova & al. (2011), however, found Schlumbergera, Hatiora s.str. and Rhipsalidopsis to form a grade, and even though support for this topology is also moderate, support for the monophyly of the three genera is maximal, therefore Rhipsalidopsis (Easter cacti) is best kept separate from Schlumbergera (Christmas cacti).A
