Tetramolopium is a genus of plants in the aster tribe within the daisy family. Most of the species are native to New Guinea, 11 species are found in Hawaii, and one in the Cook Islands, with the island populations apparently representing a recent (by evolutionary standards) colonization. It is related to Camptacra, Kippistia, Minuria, Peripleura, and Vittadinia all of which are from Australia, New Guinea, New Zealand, or Pacific islands. see Diplostephium
