Dubious Intergeneric Hybrids

 

Intergenus crosses may not be that, but the result of flowers being tricked into acceptance of self-pollen, due to the presence of foreign pollen of botanical species. Most species and hybrids of Schlumbergera normally reject their own pollen with the exception of S. kautskyi and S. microsphaerica. The latter two are known to be self-fertile. Some of the S. kautskyi hybrids have proven to be self-fertile like the species parent.

× Schlumisocactus Süpplie (2000) – Schlumbergera × Disocactus macranthus. Several of Joyce Carr’s hybrids are described as an intergeneric cross between Disocactus and Schlumbergera. The legitimacy of this being a true hybrid has yet to be validated.

× Schlumbephyllum Süpplie (2000) – Schlumbergera × Epiphyllum. There are some hybrids described as being a cross between an Epiphyllum hybrid and Schlumbergera. The legitimacy of this being a true hybrid has yet to be validated.

× Schlumbergolychnia D.R. Hunt (1978) – Schlumbergera × Eulychnia. It seems to be a fictionary name.
