SCHLUMBERGERA RUSSELLIANA
(or ZYGOCACTUS)
(or CHRISTMAS CACTUS)
photo 8/9

This time, there is no doubt, the bloom is actinomorphic, (i.e. symmetrical compared to the axis of the pistil), as it's normal for Schlumbergera russelliana.
Thus, the identification is correct!

N.B. For greater clarity, I inserted below the photograph of Schlumbergera x buckleyi (hybrid between Schlumbergera russelliana and Schlumbergera truncata). Here the bloom is not actinomorphic but zygomorphic: in less technical terms, it is “tilted” compared to the axis of the pistil, contrary to the previous one.
