Two plants are being confused in the database, I think.
One is Curio x peregrinus (Heath 1999) (formerly known as Senecio peregrinus, also known as xBacurio delphinatifolius), common name string of dolphins

This combination does not appear in the database, though a search for Senecio peregrinus directs to this entry:
String of Dolphins (Curio x peregrinus)
Unfortunately Dendrophorbium peregrinum (Jeffrey 1992) is a different plant (not succulent, a bush), photos available here
https://www.gbif.org/species/3...
and CoL entry here
https://www.catalogueoflife.or...
The fix would be to add an entry for the Curio hybrid to the database, and move the common name String of Dolphins and images from the Dendrophorbium entry to the new one.
Rather than propose all these things, I am posting here to reduce confusion.
Note the CoL redirects to both separate listings when a search is done for Senecio peregrinus; I will let an admin decide how to handle the redundant synonym.
