Habit

Shrub or small tree to 15m, flattened ribbed, branchlets in subtropical and dry rainforest throughout Queensland and NSW.

Leaves are compound with mostly 6 leaflets, sometimes fewer. The leaves are alternate but the leaflets are opposite. Virtually no petiolule, somewhat swollen emerging from branchlet. Green above, paler below. Margins toothed, especially in upper half of leaflet.

Leaflets lanceolate, tapering to a fine point, somewhat rough and dry feeling to touch due to the raised venation (especially on the upper surface) and the toughness of the surface.

Flowers are pink to cream, October to December.

Fruit is a brownish capsule with 1-3 black seeds enclosed in a flesh red, edible aril.

Propagate from fresh seed, can be erratic. Birds spread seeds after eating the red aril.
