Acronychia oblongifolia

A tree growing to 25 m or so tall, spreading to several metres wide.

It id found from near Gympie in central-eastern Queensland, south through the extent of coastal New South Wales to a few rainforest communities in eastern Victoria. Its natural habitat is rainforest and rainforest margins.

The trunk is dark brown and generally smooth, sometimes with fine wrinkles, fissures or pustules.

The Acronychia genus has species with leaves appearing compound (3-foliolate) or simple (1-foliolate). In this species it is the latter where compound leaves been reduced over time to having 1 leaflet, hence leaves appear simple. In this species, leaves are leathery, dark green, generally glossy, aromatic with oil dots numerous and obvious, arranged in opposite pairs, to 120 mm long and to 50 mm wide, obovate to elliptic in shape.

When a Rutaceae species has opposite leaves, it tends to have 4-merous flowers (parts in 4s) and that is the case here. The flowers are creamy-white and produced in leaf axils and create much interest. They are arranged in small groups to 60 mm long. Each flower is about 10 mm wide with four sepals are and four petals, and eight stamens that alternate in length (usually 4 are longer with a shorter stamen following each longer one in the whorl, making an interesting symmetrical pattern).

Flowering occurs from February to June.

The fruit is a fleshy, white, yellow or purplish drupe to about 10 mm wide, spherical in shape, that matures from May to December.  The fruit is four-lobed and has tufts of hairs on the end.
