The Leichhardt tree is a magnificent rainforest tree with very showy blossoms borne on large flowerheads. Each flowerhead is about 5cm across. It is instantly recognizable, even without flowers, by the large leaves (up to 30cm long and over 15cm broad) and conspicuous rounded stipules. The fruits are edible.
There are some species with similar flowers. Anthocephalus chinensis is very similar with somewhat equally large leaves and flowerheads. The flowerheads of A. chinensis are more crowded however, and the stipules are smaller and pointed. Neonauclea glabra is also similar but the leaves are much smaller and the flowerheads are only about 1.5cm across.
