About 34 years ago my sister bought a plant of what was labelled "Rhipsalidopsis rosea" at the local village shop in NW England. 34 years later, in southern Spain, I have the only surviving one of many cuttings taken from this plant, most of which died from neglect despite enduring some amazingly low winter temperatures over the years. Needless to say, I am lovingly nurturing my plant! I´ve noticed that on CactiGuide "Rhipsalidopsis" isn´t mentioned. Has the genus been merged into something else or did it never really exist? My plant has compact untoothed jointed stems like a miniature Schumbergia and is smothered with clear pink flowers in Spring.
