Five new species of Rhodamnia (Myrtaceae, Myrteae) from New Guinea

Abstract. Five new species of Rhodamnia are proposed for New Guinea, including Rhodamnia asekiensis, Rhodamnia daymanensis, Rhodamnia makumak, Rhodamnia taratot, and Rhodamnia waigeoensis. Rhodamnia sharpeana, known previously only in Australia, is reported for the first time for Papua New Guinea. Detailed species descriptions and associated taxonomic data are provided for all species. A key is provided for species of Rhodamnia with stellate trichomes. Given the overall paucity of collections, all species are tentatively assigned as Data Deficient following IUCN conservation recommendations.
