Description

A shrub or small tree to 6 metres tall with a stem diameter of 5 cm. An attractive plant with pinkish red new growth in springtime and colourful fruit in the autumn.

The trunk is crooked, and not buttressed. With dark grey or black bark, marked with vertical lines and cracks. Small branches are relatively thick, shoots and branchlets show rusty brown hairs.

Leaves

Compound leaves are 35 to 45 cm long with 16 to 24 leaflets. Oblong-elliptic or reverse lanceolate in shape. Leaflets 6 to 13 cm long, 2.5 to 5 cm wide,[2] sub opposite or alternate on the stem. Leaflets sharply and prominently toothed. Leaflets asymmetrical at the base. Dark green above, paler underneath. The main leaf stem is 8 to 16 cm long. The leaflet stem 1 to 3 cm long. Smooth but channelled on the upper side.

The leaflet has around 15 pairs of lateral veins, ending in a leaf tooth. Leaf venation is more easily seen under the leaf. The midrib is sunken above the leaf, but raised under the leaf.

Flowers, fruit & regeneration

Pink flowers form on panicles from the leaf axils from July to October. The fruit is an orange red capsule with three lobes, around 2 cm in diameter. Inside the capsule is yellow aril surrounding one to three shiny black seeds, 15 to 20 mm long. Fruit matures from October to November. Regeneration from fresh seed is unusually fast, with most seeds germinating after a week or two.
