The southernmost limit of natural distribution is Port Stephens (32° S) in New South Wales, extending north to Cape York at the northernmost tip of Australia. The generic name Arytera is from the Greek for 'cup', referring to the cup-shaped fruit valves. The specific epithet divaricata is from Latin and refers to the wide-spreading branchlets of the flower panicle.
Description
editA small to large tree with dark mature leaves, reaching a height of over 35 metres, though usually seen less than ten metres tall. The base of the tree is somewhat flanged. The bark is thin, smooth and greyish.
The leaves are pinnate and alternate, of two to six pairs of leaflets. Leaf shape is lanceolate to ovate, not toothed. Leaflets are 5 to 15 cm long, 1.5 to 6 cm wide, hairy and leathery, and usually not with a sharp point. They are shiny green above. New foliage is red, pink then yellow. The leaf stem is 3 to 6 mm long. The midrib is raised above and below. Leaves are distinctly veined, with 8 to 12 main lateral leaf veins.
Flowers form between November and April, being cream in colour, on wide and hairy panicles. The fruit is a capsule with three lobes. Brown oval-shaped seeds are enclosed in a red fleshy aril. The seeds mature from June to October. Seed germination is reliable, often taking only seven days for roots to show.
Uses
