Pisonia is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae.
 It was named for Dutch physician and naturalist Willem Piso (1611–1678).
 Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because their sticky seeds reportedly trap small birds.
 These sticky seeds are postulated to be an adaptation of some island species to ensure the dispersal of seeds between islands by attaching them to birds.
 These island species include "P. brunoniana" of Australasia and Polynesia and "P. umbellifera", which is widespread in the tropical Indo-Pacific region.
Pisonia siphonocarpa is a species of plant in the Nyctaginaceae family.

 It is endemic to the Tuamotus in French Polynesia with recent records from the atolls of Matureivavao, Rangiroa, Tenararo, Morane, Vahanga and perhaps Tikehau.
 It favors tropical forests, especially with "Pandanus tectorius", "Pisonia grandis" and shrubs, but it has also been recorded from dense shrub growing below coconut palms.
 It is threatened by habitat loss and predation by introduced species such as cats and rats.
 The total population is estimated to be around 100-120 birds and it has already disappeared from several islands where it formerly occurred.
