''Cyanea copelandii'' is a rare species of flowering plant in the bellflower family known by the common name treetrunk cyanea. It is endemic to Maui, where there are no more than 250 individuals remaining in the wild. It is a federally listed endangered species of the United States. Like other ''Cyanea'' it is known as ''hāhā'' in Hawaiian.〔(Hawaiian Native Plant Genera: ''Cyanea'' )〕 There are two subspecies of this plant, but one, ssp. ''copelandii'', is thought to be extinct.〔Bruegmann, M. M. & V. Caraway. (2003). (''Cyanea copelandii'' ). IUCN Red List of Threatened Species. IUCN 2010. (www.iucnredlist.org ). Retrieved on 25 February 2011.〕 It was native to the island of Hawaii, where it was driven to extinction by feral ungulates such as pigs. The plant was probably also pollinated by Hawaiian honeycreepers, many of which are also extinct.〔Bruegmann, M. M. & V. Caraway. (2003). (''Cyanea copelandii'' ssp. ''copelandii'' ). IUCN Red List of Threatened Species. IUCN 2010. (www.iucnredlist.org ). Retrieved on 25 February 2011.〕 The remaining subspecies, ssp. ''haleakalaensis'', has been reduced to a population under 250 by habitat degradation caused by exotic plants and feral non-native animals. The population is divided into three subpopulations. They are shrinking by 25% each generation.〔Bruegmann, M. M. & V. Caraway. (2003). (''Cyanea copelandii'' ssp. ''haleakalaensis'' ). IUCN Red List of Threatened Species. IUCN 2010. (www.iucnredlist.org ). Retrieved on 25 February 2011.〕 This Hawaiian lobelioid is a short-lived shrub which grows as a vine. It occurs in wet and moist forests.〔 ==References==
