Hymenosporum flavum, or native frangipani, is a rainforest tree which is native to Queensland and New South Wales in Australia and New Guinea. It is the sole species within the genus Hymenosporum, and is closely related to the widespread genus Pittosporum.
It produces clusters of fragrant flowers in spring (September to October) which are about 5 cm in diameter. They are cream in colour, ageing to yellow and are followed by long pear-shaped seed capsules. The flowers attract bees and honey-eating birds and butterflies. It has dark green, glossy leaves which are usually around 10 cm long and 4 cm wide. At its best, the branches are heavily foliaged and form widely spaced tiers which makes the tree extremely attractive.
Despite its common name, it is not closely related to the frangipani.
