Are Sinningia and Hyoscyamus in the same family?
Hyoscyamus Hyoscyamus — known as the henbanes — is a small genus of flowering plants in the nightshade family, Solanaceae. It comprises 11 species, all of which are toxic. It, along with other genera in the same family, is a source of the drug hyoscyamine (daturine).
Johannesbaptistia Johannesbaptistia is a genus of brackish–freshwater cyanobacteria which has a very characteristic morphology. It is the only member of the family Cyanothrichaceae. When the name was changed from "Cyanothrix" to "Johannesbaptistia" (due to the rules of priority in the International Code of Nomenclature for algae, fungi, and plants), the family name was not changed.
