Bidens cosmoides, commonly known as the cosmosflower beggarticks, is a species of flowering plant in the sunflower family. It is endemic to mixed mesic forests at elevations of 2,000–3,000 ft (610–910 m) on the island of Kauaʻi in Hawaii. This particular member of the genus Bidens is far larger than its relatives and is pollinated by birds. Unlike its smaller relatives, collectively called kokoʻolau or koʻokoʻolau in the Hawaiian language, B. cosmoides is so conspicuous and distinct that it was given a distinct name by the locals: poʻola nui ("grand poʻola"). This refers to the fact that the
