Polianthes

Polianthes /ˌpɒliˈænθiːz/[1] is a formerly recognized genus of plants in family Asparagaceae, subfamily Agavoideae.[2] molecular phylogenetic studies showed that Polianthes is embedded within the larger genus Agave, which has been expanded to include it.[2][3] (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.
