Catchbirdtree (Pisonia)
Description
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.
