Description: Small to large trees, glabrous or with simple, scale-like or stellate hairs, unarmed.
Leaves alternate to opposite, simple, 1-foliolate, 3-foliolate to paripinnate or imparipinnate; leaflets 1–16, margins entire; lateral leaflets opposite or almost so.
Inflorescences axillary in the upper axils or terminal, paniculate. Flowers bisexual or functionally staminate. Sepals 5, free or basally fused. Petals 5, imbricate, free, not persistent in fruit. Stamens 5, free, erect with inflexed apices, opposite the sepals, alternating with 5 staminodes. Ovary 5-locular, shallowly 5-lobed, ± globose, usually with 5 apical glands around the base of the fused styles; styles arising terminally from carpels; stigma capitate or peltate; ovules 4–6 in each loculus.
Fruit a ± woody capsule opening septicidally into 5 valves; seeds winged, falling from dehiscing fruit, dull to shiny, brown.
Distribution and occurrence: World: 16 species, Moluccas, New Guinea, New Caledonia. Australia: 14 species (11 species endemic), Qld, N.S.W.
Many rainforest species yield timber that is widely used for flooring, cabinet work and other interior fittings. F. australis is one of the most valuable of Australian timbers.
