Owenia is a genus of plants, mainly trees in the mahogany family Meliaceae. They are endemic to Australia and fairly widespread across the continent. There are five species in the genus, most from New South Wales and living in conditions ranging from wet rainforest to the verges of the desert. Like many plants, it plays its part in patch dynamics.
One, O. cepiodora, is rare, and is renowned for having freshly cut bark that smells of onions. Its common name is Onion Cedar or Bog Onion.
