Polyalthia is a genus of flowering plants in the family Annonaceae. There are approximately 90 species distributed from Africa to Asia and the Pacific.^[1]

These are trees and shrubs. The flower has six petals in two whorls, the inner petals curving inward over the centre.^[1]

The name Polyalthia is derived from a combination of Greek words meaning 'many cures' with reference to the medicinal properties of certain species.^[2]

Species

This large genus was known to be polyphyletic, with many species having been separated and reassigned to other genera.^[3]^[4] Species have also been transferred into this genus (e.g. P. malabarica from Phaeanthus).

As of January 2025^[update], Plants of the World Online accepts the following 98 species:^[5]
