Genus Cyanea
Cyanea may be:Species in the genus Cyanea of plants
Honolulu cyanea - Cyanea acuminata is a rare species of flowering plant known by the common names Honolulu cyanea. It is endemic to Oahu, where there are no more than 250 individuals remaining.
Gingerleaf cyanea - This Hawaiian lobelioid is a small, short-lived shrub. The leaves are heart-shaped and the inflorescence bears up to 40 flowers which are white with purple stripes.
Treetrunk cyanea - There are two subspecies of this plant, but one, ssp. copelandii, is thought to be extinct.
Koolau Range rollandia - Cyanea crispa is a rare species of flowering plant known by the common names crimped rollandia and Koolau Range rollandia. It is endemic to Oahu, where there are no more than fifty individuals remaining in the Ko?olau Range.
Long-foot cyanea - This Hawaiian lobelioid was discovered in the Blue Hole, a valley on Kauai near the Wailua River. The Blue Hole is deep, nearly surrounded by steep cliffs up to 900 meters tall, and wet, a very high rainfall area filled with waterfalls. Only four plants were ever found, three juvenile specimens and one plant just reaching flowering stage. Because the plant was so obviously an unknown species and was apparently on the brink of extinction, it was given a name. It was not seen again after 1992.
Ravine cyanea - This Hawaiian lobelioid is a branching shrub which grows in wet and moist forests and gulches in the Molokai Forest Reserve.
Cyanea eleeleensis - Cyanea eleeleensis is a rare species of flowering plant in the bellflower family known by the common name Eleele cyanea. It is endemic to Kauai, where there are no more than ten plants remaining in the wild.
Smooth cyanea - This Hawaiian lobelioid is a branching shrub that reaches an uncertain height.
Wetforest cyanea - There are two subspecies of this species. The more abundant, ssp. hamatiflora, is native to Maui, where there are no more than 250 individuals left and the population is dropping by at least 25% per generation.
Oahu cyanea - Cyanea hardyi, known in Hawaiian as h?h?, is species of flowering plant in the bellflower family, Campanulaceae. This Hawaiian lobelioid is endemic to southern Kaua?i. It inhabits forested valleys up to an elevation of 790 m .
Sharktail cyanea - At the time this plant was federally listed as an endangered species in 1991 there was only one individual left. It grew in the Waianae Mountains of Oahu until 2001, when it died. Now some plants are kept at the Lyon Arboretum in Honolulu and a few juveniles have been planted in appropriate habitat. No recruitment has occurred among these, however, and the plant is still considered extinct in the wild.
Molokai cyanea - This plant has been reduced to very low numbers. At one time it was thought to be extinct.
Kaiholena cyanea - This Hawaiian lobelioid is a shrub or tree of the rainforest. It has become rare due to the grazing and trampling damage of cattle. There are perhaps 20 individuals remaining.
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.
Punaluu cyanea - By the 1980s this Hawaiian lobelioid was known only from the Ko?olau Mountains of Oahu, and the last plants were seen in 1983.
