Sessea is a genus of 19 accepted species of shrubs, small trees and climbers belonging to the subfamily Cestroideae of the plant family Solanaceae. The flowers of Sessea are so similar to those of Cestrum that the genera cannot usually be told apart, unless the plants are in fruit. Then their distinguishing characteristics become immediately apparent; plants of the genus Sessea bearing dehiscent capsules dispersing winged seeds, while those belonging to the genus Cestrum bear juicy berries containing prismatic seeds. The flowers of both Sessea and Cestrum have tubular corollas that are long exserted from small calyces.
