Looking at Hippeastrum in the Plant database, the word AMARYLLIS would need to be removed from each entry and a Note would need to be added to say that includes Genus Hippeastrum species and hybrids/crosses and no other members of the Amaryllidaceae Family.
The Amaryllis PlantDB would either have to only list the two species and cultivars within them.
An Amaryllidaceae Family/Hybrid Alliance Maybe?
