Eucalyptus kochii, commonly known as oil mallee, is a native tree of Western Australia.
There are two subspecies:
- Eucalyptus kochii subsp. kochii
- Eucalyptus kochii subsp. plenissima
It is cultivated in plantations for the production of eucalyptus oil. The distilled oil has a very high content of cineole (83-94%).
