''Brighamia rockii'', known as the Molokai ohaha or ''Pua ala'' in Hawaiian, is a species of flowering plant in the bellflower family, Campanulaceae, that is endemic to the island of Molokai in Hawaii. ''Pua ala'' inhabits mesic shrublands and forests on rocky cliffs from sea level to on the island's northern windward coast. Associated plants include ''ōhia lehua'' (''Metrosideros polymorpha''), ''alahee'' (''Psydrax odorata''), ''lama'' (''Diospyros sandwicensis''), ''ūlei'' (''Osteomeles anthyllidifolia''), and ''naupaka'' (''Scaevola gaudichaudii''). ''Pua ala'' reaches a height of and has a succulent, trunk-like stem that tapers from the base. The oval-shaped leaves are long and wide and form a rosette on the top of the plant. Each inflorescence contains three to eight trumpet-shaped white flowers. ==Conservation== ''Pua ala'' has been extirpated from the islands of Lānai and Maui. Threats to its survival include habitat loss, competition with alien plants, predation by goats and deer, and a lack of pollinators.〔 There are five occurrences of the plant remaining in the wild, with a total estimated population of fewer than 200.〔(The Nature Conservancy )〕 It is federally listed as an endangered species. Some individuals have been cultivated and planted in the habitat.〔USFWS. (''Brighamia rockii'' Five Year Review. ) January 18, 2008.〕
