Polianthes is a formerly recognized genus of plants in family Asparagaceae, subfamily Agavoideae. molecular phylogenetic studies showed that "Polianthes" is embedded within the larger genus "Agave", which has been expanded to include it. (See "Agave" § Taxonomy.) One of its former members is the tuberose, "Agave amica", formerly "Polianthes tuberosa", a plant that is commonly used in perfume making.
