The common name of this attractive and elegant fig, the Small leaved fig is not really accurate and pretty uninformative for getting to know it.
Figs are in a class of their own, and it is not difficult to tune into their distinctiveness, sometimes to the point that one may recognize many species just by sight. To describe this distinctiveness is another thing altogether.
I suppose that as Australian fig trees go, Ficus obliqua does have relatively small leaves (~5-12cm) but it is by no means the smallest. However, this fig tree can get rather huge, with large buttressed trunks and reputably attaining a height of up to ~60m (according to Wiki), occurring as rain forest emergents. In open areas it can also spread out widely. I would certainly love to be in the presence of such giants.
Most times I have seen it as a medium sized tree maybe up to about 10m, but also as a shrub a few meters high on rocky areas by the coast and also inland.
I know nothing of this tree’s native use here but in Fiji the tree was held as sacred and there is a tradition of medicinal use for this tree for a range of ailments. Ficus obliqua is also a popular bonsai plant.
