White flowers form on [[panicles]] in the months of November to December. Petals five in number per flower, around 4 mm long. The fruit is red drupe, with white pulp. 1.5 to 2 cm in diameter with two, three or four cells, each with usually two seeds. Fruit matures from January to March. Regeneration is unreliable, however germination should commence around November to January. |

| Owenia cepiodora | |
Owenia cepiodora is a medium to large Australian tree in the mahogany family. It occurs in the rainforests of north eastern New South Wales and adjacent areas in Queensland. The habitat is mostly the drier Hoop Pine rainforests along the state border. Only small regrowth trees remain, as it was heavily logged in earlier times. Its status is now considered vulnerable with a ROTAP rating of 2VCi.
Common names include Onion Cedar, Onionwood and Bog Onion. The timber resembles the valuable Australian Red Cedar. Logs were soaked to remove the characteristic onion scent and sold as Red Cedar. The species name refers to the onion scent.[1] It is found as far south as the Richmond River and as far north as Canungra, in the Gold Coast hinterland.
