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.
