Mt. Kaala cyanea

This Hawaiian lobelioid was known from lowland forest habitat in the Waianae and Ko?olau Mountains of Oahu. There were two subspecies. The ssp. regina has not been seen since 1932 and is considered extinct.

Cyanea superba was endemic to the island of O'ahu, Hawaii. It was known from the northern Waianae Mountains and the southern Koolau Mountains. Only the Waianae subspecies superba was known to be extant. More than 60 plants in two subpopulations were known in the 1970s. The subspecies (and species) then declined down to only one subpopulation containing about five plants. But those too have now finally gone. More
