structures in their stems being better established. The leaves are reduced to small scales, and the green, drooping stems are the site of photosynthesis. Its inconspicuous flowers are arranged in clusters on short spikes 3–6 mm long. Only one flower on each spike forms a fruit. The inedible fruit is a globular, hard, greenish nut, 4-6mm long, containing one seed. It is found on top of a short

. The true, seed-like fruit (actually a nut containing the seed, like the acorn) is found on the outside of the fleshy false "fruit" (actually a swollen pedicel), hence the original name ''Exocarpos'', from the Latin meaning ''outside fruit''.

s. The pale wood is very fine-grained with little figure, but often with striking colour variation. The timber was historically used for making furniture, gun-stocks, and tool handles. It is also suitable for carving and turning, so is now used for producing decorative and ornamental pieces of art and craft work. The fleshy pedicel, the "cherry", is edible, and was used as food by indigenous Australians and by early European settlers. The "fruit" is picked when it is so ripe that it is ready to fall from the tree. It may be eaten raw or cooked. The 1889 book, ''The Useful Native Plants of Australia'', records that Indigenous Australians in Queensland referred to the plant as "Tchimmi-dillen" or "Coo-yie", and that "The fruit is edible. The nut is seated on the enlarged succulent pedicel. This is the poor little fruit of which so much has been written in English descriptions of the peculiarities of the Australian flora. It has been likened to a cherry with the stone outside (hence the vernacular name) by some imaginative person." Early European settlers used branches as

Dispersal and propagation

Birds feed on the "cherries". They are attracted to the colourful pedicel to which the nut is attached. The digestive juices of the bird weaken the hard nut, allowing the internal seed to germinate more easily. Propagation of the species has proved to be difficult.
