Polianthes

Polianthes is a genus of flowering plants in family Asparagaceae. It includes 23 species native to Mexico. One of its species is the tuberose, Polianthes tuberosa, a plant that is commonly used in perfume making.

==Taxonomy== Polianthes and close relatives have long presented significant taxonomic difficulty. With the advent of DNA sequencing, new karyologic and evolutionary phylogenetic studies showed that Polianthes, along with Manfreda and Prochnyanthes, were genetically nested within the traditional circumscription of Agave, rendering that genus paraphyletic. Early in the 21st century, these new phylogenetic results led to a reclassification of to include Polianthes, Manfreda and Prochnyanthes together as Agave subgenus Manfreda.
