Flowers:                  

• Yellow brown flowers form in November, from the forks of the leaves

• Individual flowers around 4 mm in diameter

• Male flowers in axillary racemes with a perianth around 2 mm long, with 5 to 10 stamens

• Female flowers solitary or in clusters of 3 or 4

Fruit:                         

• The fruit is a bright red drupe. 12 to 20 mm long with moist yellow flesh inside

• The single seed is about 12 mm long, oval in shape with a groove on one side

• Fruit mature from February to April

• Eaten by the emerald dove, topknot pigeon and wompoo fruit dove

• Germination from seed is slow

Leaves:         

• Elliptical, ovate to ovate-oblong in shape, 4 to 9 cm long, 1 to 5 cm wide

Stem & branches:    

• The tree is often flanged at the butt and lower part of the trunk

• Grey or brown bark, often with scales of bark which fall, leaving shallow depressions

• This results in a mottled appearance, similar to the tulipwood

Additional notes:     

• Uses

  • Previously used as bullock whip handles, in the Richmond River district, northern NSW

  • Indigenous Australians ate the fruit raw, and used leaves in cooking, as well as carving the wood

  • Early settlers on Lord Howe Island used the timber for sea piles because the sap repels marine worms

• Ecology

  • A food source for a variety of insects

  • Such as the common albatross butterfly

  • Possibly also a food source for the critically endangered Lord Howe Island stick insect
