Nothocestrum breviflorum remaining. Nothocestrum breviflorum Nothocestrum breviflorum, commonly known as smallflower aiea, is a species of tree in the nightshade family, Solanaceae, that is endemic to the island of Hawaii. It inhabits dry and mixed mesic forests at elevations of . These forests are dominated by ōhia lehua ("Metrosideros polymorpha") and koa ("Acacia koa") or lama ("Diospyros sandwicensis"), while plants associated with smallflower aiea include wiliwili ("Erythrina sandwicensis") and uhiuhi ("Caesalpinia kavaiensis"). "N. breviflorum" reaches a height of . It is threatened by habitat loss. It is federally listed as an endangered species of the United States. There are fewer than 50
Greater koa finch regeneration of koa forests, while introduced black rats ("Rattus rattus") preyed on young birds. Avian pox ("Poxvirus avium") and malaria ("Plasmodium relictum"), spread by mosquitoes, may have also been a factor. However, even before these issues became important, the koa finches were probably already living in marginal habitat due to the loss of lowland koa forests, as evidenced by the extinction of the other koa finch species (which lived on lower-elevation islands) prior to European contact. Greater koa finch The greater koa finch ("Rhodacanthis palmeri") was a species of finch in the Fringillidae family. It was found only in the
