All currently assessed
Brugmansia species have been listed as Extinct in the Wild, however, they are popular ornamental plants that have been cultivated around the world.
Cyanea superba was once found on the island of
O'ahu , Hawaii until it became Extinct in the Wild, mainly due to competition and habitat destruction from
invasive species and wildfires generated by human activity.
The extinction in the wild of
Kokia cookei is largely believed to be a
coextinction with native nectivorous birds, which may have pollinated it.
