The species
Cerbera odollam — evergreen tree or large shrub from the Apocynaceae family, a close relative of the equally deadly oleander. It grows to 10–12 m tall, with dark glossy leaves, large white flowers with a yellow center, and ellipsoid red fruit that ripens to a glossy deep red — beautiful, and a bait for anyone who bites.
Where it grows: sandy tropical coasts, riverbanks, mangrove in South and Southeast Asia, the Pacific islands, and the coast of Queensland. It is also planted as a decorative tree in gardens from Hawaii to Dededo (Guam) — meaning you can walk up to it in a courtyard, not in the jungle.
