I have a problem with the many suggestions to move various images to the entry for Kalanchoe x houghtonii. The fact is that this entry does not even belong in our database because it's not a valid botanical name. The hybrid taxa that are included in the major taxonomic databases and our database are hybrids that occur spontaneously, in the wild. This name was added to our database in error because Kalanchoe x houghtonii is a man-made hybrid of K. daigremontiana and K. delagoensis and therefore is not a taxonomically acknowledged hybrid taxon. The synonym included in our present entry, Bryophyllum x houghtonii, is not included in the taxonomic databases as an accepted name or synonym either.
Mother of Thousands (Kalanchoe 'Houghtonii')
The only solution I can see is to rename this entry to show Houghtonii as the cultivar name, with Kalanchoe x houghtonii and Bryophyllum x houghtonii listed as also-sold-as names.
