While there are 6 defined species of Schlumbergera, they readily hybridize both in the wild and under cultivation. For this reason, it is more useful to classify the cultivars into groups based on their characteristics.
- Pointed teeth
- Zygomorphic Flowers held horizontally (slightly above)
- Yellow pollen
- Rounded, more symmetrical teeth
- Regular flowers that hang below the horisontal
- Pink pollen
- Sub groups
- TB - Mostly like Buckleyi, but with strong Truncata traits
- BT - Mostly like Buckleyi, but with slight Truncata traits
Currently, all plants except C show signs of overexposure to the sun, resulting in the shades of yellow and pink visible in the stem segments, rather than the deep green that is expected.
- Specimen A
A blooms are a bright red with slight salmon hues. The pollen is a light yellow. It appears to be a member of the Truncata Group, largely due to the sharp spines.
